Ecological productivity is one of the ancient magical and tremendously powerful natural reaction. Human and human social production, evolution and development, the social productive forces and natural nature twices generation and evolution development and present profusion multifarious natural phenomenon, are ecological productivity masterpiece, ecological productivity is worthy of the creator. In human haven't unravel the mysteries of ecological productivity, before the ancients consistent the ecological productivity as creator, as omnipotent god's score a lucky hit to ecological productivity do the objective description and accurate interpretation, and ecological productivity produced cannot use digital to measure biological resources, created can not use words to express the ecological value. Ecological productivity--creator, ecological productivity-- god, this overview is human, human society, the social productive forces, evolution of nonresonant-type deciphering the driving force of development, Also on human, human society, the social productive forces and biological and ecological system, nature of the relation between accurately reveal, But for human, human society and social productivity evolutionary direction of science leads. To develop the productive forces, we must first cherish, protection and development of ecological productivity.

The recovery, develop and strengthen the ecological productivity, as the development of the social productive forces, enhance the ability of sustainable development of mankind, place the fundamental measures to the nation and even the global security and development strategy of the first, for the power of the global development priority.
A, ecological productivity essence
Ecological productivity, is the biological and ecological system in accordance with the laws of nature evolved in the process of the production of biological material and biological energy, in the role of nature and promote nature evolutionary development, create ecological value embodies the natural reaction.
(a) the ecological the connotation of productive forces
In the view of the political economics, productivity means all forms of productive labor body (including labor tools) in labor process released by the effective role in labor object, change labor object form and make it become the new use value of effective reaction. Referring to a human labor production activities after the social productive forces. Ecological productivity, from the Angle of ecosystem productivity of production and service function make conceptual interpretation. Ecological productivity, as biological and ecological system, with the appearance of produce biological, ecological system's development. The ecosystem is the carrier of ecological productivity, ecological productivity is the essence of ecological system and soul.
1.the concept of ecological productivity. Ecological productivity, is the biological and ecological system in the development process of the production of biological evolution unceasingly, pass biological material energy, in the role of nature and promote nature evolutionary development, create ecological value for human being, production and life create, accumulate and storage biological material and biological energy for human survival and development, continuous improvement and optimizing environment conditions released by the natural reaction.
Ecological productivity, is the biological and ecological system in the process of their own evolution development and bring into play the production and service functions, create ecological value released by the natural reaction.
Ecological productivity, green plants, blue-green algae, photosynthetic bacteria etc autotrophic organisms through photosynthesis production and accumulation plant, microbial form of biological materials and biological energy, heterotrophic organisms (all kinds of animal) and absorbs autotrophic creature of biological nutrient, provide production animal form of biological materials and biological energy jointly reflect the production and service ability.
Ecological productivity of value, reflected in the biological and ecological system in their own evolution process of development and bring into play the production and service functions, and promote the development and evolution of nature for human survival and development provide biological material and biological energy, optimize the survival and development of the ecological environment.
Ecological productivity, as well as for all living organisms of biological productivity and service function, and embodied in a single biology and biological communities, between biological communities and ecological system, between ecological system and nature, between human activities and the nature harmonious balance between capacity, harmony evolution released interactivity, complementary, coordination wholeheartedly. Ecological productivity from biological productivity, and higher than biological productivity.
On the ecological productivity of discovery, knowledge and recognition, broke through the productivity of traditional category, expand the productivity of denotation, enrich the connotation of productive forces, make productivity become already inclusive society productivity, and contains ecological productivity of binary body.
2. the principle of ecological productivity. Ecological productivity, fully embodies the principle of biological perform primary production in autotrophic heterotrophic organisms to perform the function and production function, the production of biological secondary substances and biological energy independent production function.
(1) the primary production function. Refers to the green plants, blue-green algae, photosynthetic bacteria etc autotrophic organisms, pass photosynthesis production, accumulate and storage plants and microbes form of primary biological material and biological energy efficiency. The primary production function by the production of products is ecosystem and natural food source for ecosystem material transformation and energy transfer offers inexhaustible and inexhaustible biological resources, ecological system of matter and energy circulation foundation. This creature by autotrophic production, accumulated, and storage of the primary biological material and primary biological energy, called the primary production; Its production, accumulation and storage primary biological material and primary biological energy effect, known as the primary ecological productivity. (2) subprime production function. It is means that the consumption function and the decompose function of heterotrophic organisms reflect production efficiency. Firstly, consumers through ingestion autotrophic creature of production functions products, production and animal form of biological materials and biological energy. Secondly, disintegrator through decomposition, degradation, feeding animals and plants remains and animal waste production animal form of biological materials and biological energy, and animal and plant remains and animal waste decomposition, soil degradation after integration service function of return. Heterotrophic organisms feed, consumption primary products and decomposition, degradation, feeding animals and plants remains, animal waste and realize own growth, development, reproduction development in the course of production, accumulate and storage animal form of biological materials and biological energy, called subprime production; Its production, accumulation and storage animal form of biological materials and biological energy effect, known as the subprime ecological productivity.
(b) the features of ecological productivity
The essence of ecological productivity is primary productive function and subprime productive function played by biological and ecological system in the process of natural evolution development , create ecological value released by natural force, fully embodies the ecological productivity naturalness, primitiveness, extensiveness characteristics.
1. It is the natural productivity. Implementation secondary primary production and production activities are the subject of natural ecosystem autotrophic organisms and heterotrophic organisms. Ecological productivity production of biological material and biological energy utilization of resources, is from the nature of sunshine, air, water, soil fertility and other natural resources. Ecological productivity production of biological material and biological energy force is the biological and ecological system in their own evolution of release of the development process of natural reaction. Ecological productivity production of biological material and biological energy process, is the biological and ecological system itself evolved natural processes. Ecological productivity by the object function is nature's natural resources. Created by the ecological value, is the biological and ecological system in their own evolution in the process of the evolution of phenomenon accompanied. Ecological productivity originated in nature, the development and the nature and function of natural forces in nature.
2.It is original productivity. Ecological productivity and generation function, is dating 10 billion years ago, in ancient times just as the earth's original biological and original ecology system develops and produces, as biological and ecological evolved and evolved, than human history more than 10 billion years old. Early At present about more than 10 billion years ago, in ancient times, the earth's atmosphere almost nothing to oxygen, the earth's oceans appeared adaptation of anaerobic respiration in algae, terrestrial appeared on the adaptation of anaerobic respiration in microbial, they rely on photosynthetic pigment, use the sun light energy for photosynthesis, carbon dioxide into organic matter and release oxygen, both original primary production function, and gave birth to the most original ecological productivity. Then successively on land appeared to have anaerobic respiration function of lower plants. And as photosynthesis and release oxygen increases and accumulation, having the aerobic respiration of higher plants, its photosynthetic function increasing, photosynthesis daxincun is perfect, and formed the autotrophic organisms and heterotrophic organisms, terrestrial and Marine life a virtuous circle of the big biosphere, ecological productivity ever-improving, mature. Ecological productivity germination in dating 10 billion years ago, produced in 7 billion - 8 billion dating and matured in dating from 4.5 billion years ago. Far more than 300 million years in human history to old. Visible, ecological productivity is the most primitive natural productivity.
3.It is widely productivity. Ecological productivity, one is by autotrophic organisms production plants and microbes form of biological materials and biological energy released by the primary ecological productivity, 2 it is by heterotrophic organisms production animal form of biological materials and biological energy released by the subprime ecological productivity. Whether autotrophic organisms or heterotrophic organisms, whether low-level biological or senior biological, whether Marine biological or terrestrial, whether a plant or animal, the earth's 400 million (some say more than 400 billion) biological, each biological communities and the entire ecosystems, are biological material producers and biological energy of the message. Visible, ecological productivity, is the most common and most extensive natural productivity.
(c) The relationship of ecological productivity and social productivity
All human productive activities without the biological resources created by ecological productivity, human development social productivity is the transformation and sublimate of ecological productivity, ecological productivity is material base and energy sourcethe developing the social productivity, both between is the relationship of cause and effect.
1.ecological productivity is the source of development of the social productive forces. Biological and ecological system by the production of biological materials and biological energy, is human development of the social productive forces, create production and living material must rely on biological resources. Exploitation and utilization of biological materials and biological energy, is human development of the social productive forces and grants.
(1) the development of the social productive forces of biological resources from ecological productivity. Biological material and biological energy is the development of the social productive forces is necessary resources, while all biological material and biological energy and orginate from ecological productivity of the production function. Whether autotrophic organisms implementation photosynthesis accumulated and storage plants and microbes form of biological materials and biological energy, or heterotrophic creature production, accumulate and storage animal form of biological materials and biological energy, all is the creation of ecological productivity results. Can say, no ecological productivity created of biological materials and biological energy, there would be nothing to development of the social productive forces biological resources, mankind can't produce material material, cannot create social wealth, there can be no social productivity.
(2) the ecological productivity contributed to development of the social productive forces subject. Ecological productivity is the source of development of the social productive forces, but also embodied in ecological productivity this creator contributed to development of the social productive forces, and the subject of human society.
Human same as other animals, are from simple to complex biological, biological creatures from lower to higher biological evolved. In experience from primitive fish to amphibians, by amphibian to reptiles, from reptiles to mammals, by mammals to primates, by primates to apes animal long evolutionary process after, just had dating from the apes animals to about 300 million years ago evolution to senior animals -- human evolution results. Visible, if no ecological productivity to promote development of biological evolution, and no human, no development of social productive force subject may not have social productivity.
2.Both between is the relationship of decision effect and counterproductive. Ecological productivity is the development of social productivity and energy source material base, the development of the social productive forces completely built on the basis of ecological productivity. Therefore, ecological productivity appearance and scale of social productivity appearance and decision scale, Social productivity for developing ecological productivity and have the ability to stimulate or hinder the role.
(1) the ecological productivity decided to development of social productive force. Human development of the social productive forces by utilizing the material resources mainly comes from ecological productivity, created by the biological resources, development of the social productive forces forever is inseparable from the support of the ecological productivity, can never get rid of ecological productivity restrictive functions. Otherwise, once the development of social productive force for demand beyond the capacity of nature, beyond the ecological productivity back-strength, will inevitably can present a ravaged and destroy mybrothers ecology, waste and wasted resources, pollution and trampling environment, fundamentally strangling the vicious circle of ecological productivity trend. Therefore, ecological productivity of the weak, the biological resources directly determine the amount of people to develop the ability and the level of social productive forces, directly determine the face of social productivity and scale.
(2) social productivity of ecological productivity has a motile reaction. Ecological productivity of social productive forces has absolute decisive effect, social productivity and to ecological productivity has a motile reaction.
1) between benign circulation of promoting the ecological productivity development. When the development of the social productive forces in the speed and scale in nature's capacity, within ecological productivity back-strength remain within the capacity of the nature, space, retain promote ecosystem and ecological productivity recovery, evolution, the full development of leeway, development of social productive force for activities on ecology, resource, environment does not constitute a pressure and harm, both between will benign interaction relationship, be helpful for promoting the development of ecological productivity.
2) when a vicious cycle block between ecological productivity development. When the development of the social productive forces in the speed and scale beyond the nature scale and capacity, people take demand beyond the ecological productivity back-strength, humans excessive demand, disorder and brutal claim for activities is the inevitable result of biology, ecology and constitutes a septuagenarian type of nature ecosystem stress, leading to the biological stock decreases, ecological system atrophy, seriously impede ecological productivity development.
B. Ecological productivity powerful production function
Ecological productivity of production functions, is the biological and ecological system play primary production function and subprime production function, production, accumulation and storing large quantities of biological materials and biological energy, create ecological value for human development of the social productive forces, provide a huge biological resources, for human survival and development environment conditions such as creating huge optimization function.
(a) photosynthesis synthesis ecological productivity development fountainhead
Autotrophic organisms by implementing photosynthesis production plants and microbes form of biological materials and biological energy, displays the formidable carbon and oxygen functions, made of carbon dioxide gas rendezvous become a huge amount of biological materials, solar energy materialized become powerful creatures energy, is the most powerful natural productivity. Only by crops and forest of photosynthesis, for example, is enough to evidence autotrophic organisms photosynthesis powerful production function. Autotrophic organisms implementation photosynthesis each to produce a ton of dry matter, will absorb 1-year tons of carbon dioxide gas, release 0.53 tons of oxygen. Or photosynthesis each to produce a ton of carbohydrates (C6H12O6), will absorb 1.47 ton of carbon dioxide, release 1.07 tons of oxygen.
In accordance with an average annual production per hectare crops 15 tons of dry matter yield (cereal production 7.5 tons, straw yield 7.5 tons) to calculate, every year 10.95 hectares of crops to absorb carbon dioxide and release 7.95 tons tons of oxygen. According to the global existing farmland 15 million hectares extrapolate, global crop annually to implement photosynthesis production 225 million tons, the absorption of dry matter 164.25 billion tonnes of carbon dioxide 119.25 million tons, release oxygen.
Every hectare forest average annual to produce 10 tons of forest tree dry matter (including root leaf). So, every hectares of forest each year to absorb carbon dioxide and release 73,000 tons of 5.3 tons of oxygen. According to the global existing forest area 38.69 million hectares of global forest every year to calculate, photosynthesis production 386.9 million tons, the absorption of dry matter 282.44 billion tonnes of carbon dioxide 205.06 million tons, release oxygen.
On land and grassland, wetland, freshwater ecosystem survival such a large amount of plants and algae, and Marine ecosystem survival with vast amounts of blue-green algae, these autotrophic organisms can also perform powerful photosynthesis. A conservative estimate ocean, grassland, wetland, fresh water and other ecological system of photosynthesis function with farmland, forest, the two major ecosystem of photosynthesis function is equal, so all global autotrophic organisms inside 1 year implementation photosynthesis production capacityof: annual production 1223.8 million tons, the absorption of dry matter 893.38 billion tonnes of carbon dioxide 648.62 million tons, release oxygen. Visible, autotrophic organisms photosynthesis synthesized earth's most powerful productivity.
(b) created a rich labor material
Ecological productivity in promoting ecosystem and natural evolution the course of development, create a vast land, breeding a lot of biological properties, economic function is admirable animals and plants varieties, to satisfy human production life needs, providing a wide range and abundant labor material.
1.built for human cultivation of the vastness of the land. Soil formation is about ten billion years ago to 500 million years ago, between the Marine plants log in, land have luxuriant plant after that the plant roots and microbial secrete plenty of enzymes, and the air oxidation of aid move under the soil layers of decomposition of parent quartz, feldspar kind, mica sort, pyroxene and Angle flash stone, iron ore type, calcite, gypsum, apatite and clay minerals such as rock) and the generated rocks, and insects, particulate organic matter, microorganism under the common function of soil amelioration and mature, promoting. Obviously, is available to humans build ecological productivity farming's vast and fertile land.
2. bred the available for human development and utilization of the abundant energy. Oil, natural gas and coal is the modern industrial production and human life's primary energy, and these energy is by the ancient times of biological remains evolved. Is the biological reproduction, ecological development, biological material and biological energy stored, accumulated, and evolution of result, is also the ecological productivity masterpiece.
(1) the plant remains evolved into coal. Millions of years ago, is coal plant remains on the ground after the accumulation of crustal lifting movement is bedded in long-term and the underground, and high temperature and high pressure air separation and catalytic effect, in a series of complicated physical and chemical change, formed the black flammable fossil - coal.
(2) biological remains evolved into oil and gas. Petroleum and natural gas chemical composition (hydrocarbons), hit their biological essence mark. Millions of years ago is luxuriant biological accumulated lots of organic matter, and the rivers runoff handling large amounts of organic matter, were brought to the low-lying semi-deep-lake or deep buried in sediment, and with the crustal lifting movement, these creatures remains some buried deep underground or submarine to, distribution in sedimentary rock strata, and in high temperature and high pressure and anaerobic environment under the long catalysis, resolve gradually evolved last it built the liquid or gas hydrocarbons - oil or gas.
3.cultivating available to human cultivation of abundant crops. Modern human cultivation of crops are all forestry from primitive plants from simple to complex, from low to high evolved. Dating from about 4.05 million years ago Paleozoic devonian started by terrestrial ferns evolved into the woods and the emergence of primitive gymnosperms¡úgymnosperms (e.g., gingko, cypresses etc)¡úangiosperms ¡ú later angiosperms ¡úhas more than 30 million of higher plant¡úfor human cultivation cropping-forestry-herbage crop varieties. In the survival, of the survival of the fittest natural evolution, mankind chose a biological performance and economic performance and wheat, rice, corn, potato, barley, sweet potatoes, soybeans, peanut, watermelon, melon, honeydew, oranges, apples, pears, peaches, lee, banana, coconut, mango, cabbage, beans, tomato and so on a series of high yield, high quality, delicious, rich in nutrients grains, fruits and vegetable crops. For humans provided rich forestry crop resources and food resources.
4.raising available to the rich human breeding animals. Modern humans bred animals, birds, fish and other animals, also are primitive animals from simple to complex, from low to high evolved. Dating from about 4.25 billion years ago, by the original fish ¡ú amphibians (jian head type) animals¡úreptile¡úinsects animals¡ú dinosaur rise¡úprimitive mammal ¡ú bags of animals¡údinosaur perish¡úmammals and birds ¡úfor the animal husbandry and poultry breeding human fish varieties. In the survival, of the survival of the fittest natural evolution, mankind chose a biological performance and economic performance and cows, horses, donkey, sheep, pigs, dogs, camels, elephants, deer, chicken, duck, goose, and various fish such as artificial breeding of animal husbandry, poultry, fish and other animals, provide mankind a lot of work and animal food resources.
C, Ecological productivity create enormous ecological value
Ecological value, it is to point to ecological productivity in promoting biology, ecology and evolutionary development of nature, in the process of continuously optimize biological and human survival and development environment conditions that embodies the integrated ecological environmental effect. Ecological productivity create ecological value service functions, and embodies in the following respects.
(a) create evolutionary development of the biosphere
Ecological productivity in promoting biological evolution and ecology system of the course of development, build the upstream and downstream biological, biological biology and biological community, biological communities and ecological system, ecosystem and nature coordination between material exchange, energy transfer balance, evolutionary development of fluent big biosphere. Rally biological, ecology and evolutionary nature the powerful force, made by many live in different areas and different environment, takes up space, has certain scale, embody certain structure, implement a production and service functions, play a role of countless biological balance coordination and biological communities and child ecological system consisting of sustainable development ability, has evolved the big biosphere.
1.inoculation largeness of Marine ecosystem. Marine and terrestrial ecosystems, including earth all biological entire ecosystem. Terrestrial ecosystems by forests, grasslands, farmland, wetland, freshwater, alpine meadows, desert, tundra eight subsystems, The Marine ecosystem by deep, offshore, coast, beach four subsystems. Oceans and land ecological system of production and service function, mainly by producers and consumers, disintegrator, environmental system four functional areas of the biological communities to perform.
(1) the inoculation producers. By sea, land ecosystem of plants, photosynthetic fungi, phytoplankton, green algae, mangrove etc autotrophic creature composition, production primary biological material and biological energy and play the role in three aspects: first for heterotrophic organisms to provide food, Redquin is the human production plant configuration of lifestyle offers biological resources, The third autotrophic organisms of carbon and oxygen functional regulating build atmosphere structure, and optimize the atmospheric environment.
(2) pregnant consumers. By sea, land ecosystem coral, animals and the heterotrophic creature composition, production subprime biological material and biological energy. On the one hand constitute the whole heterotrophic organisms of food chain, On the other hand for human production and living provides animal form food and biological resources.
(3) inoculation disintegrators. By sea, land ecosystem of bacteria, fungi, protozoa and miniature heterotrophic creature composition, play decomposition, degradation, feeding animals and plants remains and animal waste, play clean sea, land ecological environment function. Sea, land ecosystem for human survival and development with a huge biological resources and ecological value.
= 4 \* GB2 ¢ÈThe biosphere constructing circular development. Ecological productivity constructed by producers and consumers, disintegrator organic component of big biosphere. For three production function material between the conversion and energy transfer, with a huge biological material and biological energy.
(b) building up a perfect of biological materials big circle
Ecological system of biological materials transfer and biological energy transfer, is big biosphere evolved material foundation and energy source. 1. build a comprehensive biological material and biological energy big circle. In ecological productivity, under the action of an entire ecosystem became a to environment system as the carrier, by autotrophic organisms¡úabsorb sunlight, inorganic material and organic matter¡úproduction plant forms of biological materials and biological energy¡úheterotrophic organisms¡úfeeding autotrophic organisms or hunting upstream heterotrophic organisms¡úproduction animal form of biological materials and biological energy¡údisintegrator¡úfeeding, decomposition, degradation animal and plant remains and animal waste¡úproduction animal form of biological materials and biological energy¡úreturn (return) soil material transformation and energy transfer of big circle. 2. establish a complete the ecological balance of even the chain. In ecological productivity driven by an entire ecosystem became a in the sunshine, the air, water and soil nutrient for energy, the ecological system of producers, consumers, these three disintegrators production function as the basic framework, all biological joint participation, compact construction, link compact, functions and complete, powerful food chain. And with food network link, the whole biological and ecological system composed of a one thing, depend on one thing, one content service one content, one thing restrict one thing, one thing subduing one content of natural ecological balance even. Construct a complete structure, function and complete, balance coordination, orderly evolved big biosphere.
(c) create enormous ecological safety value
1, improving and optimizing the atmospheric environment. Autotrophic organisms powerful carbon and oxygen function, made continuously adjust and improve the atmospheric structure optimization, atmospheric temperature, atmospheric environment for human survival and development builds the suitable atmospheric environment.
(1) the made satisfy human survival needs rich oxygen. We every moment of absorption of oxygen, it is to pass autotrophic organisms in the long photosynthesis process, large absorb carbon dioxide and release oxygen, a lot of that improvement and accumulation and into. Has formed by nitrogen and oxygen as main body (nitrogen, oxygen makes up about 21% of 78%, carbon dioxide gas accounted for 0.03%) amenity of air.
(2) built right of the greenhouse effect. Not the greenhouse effect is bad, just the greenhouse effect deviated from the consequences of groovy values very serious. Earth if no atmosphere of the greenhouse effect, will be like the moon in the sun appears on the back of positive and between the huge hundreds of degrees Celsius temperature between day and night, as in the huge appear hundreds of degrees Celsius temperature, and completely lost biological survival conditions. Is ecological productivity through 10 million years to make good hard-working, just to remit carbon oxygen on earth built a proper and lasting stability of the greenhouse effect, creating all creatures and the development of human evolution good atmospheric environment.
(3) in the atmosphere built a huge ozone shield. Ozone is a ? ozone (O) the atmosphere of a composed mainly distributed in 20 kilometers apart from the ground to 50 km of space, called the ozone layer. Ozone is by sunshine of the ultraviolet radiation effect on oxygen produced. We know, the ultraviolet ray in sunshine is divided into two, longwave and short-wave shortwave ultraviolet ray can make oxygen (O2) to a ozone (O3); Wave ultraviolet ray can make ozone reductive into oxygen. When atmospheric oxygen molecules by short-wave ultraviolet radiation, oxygen molecules can decompose into atomic state, extremely easily with oxygen oxygen produces chemical reaction generated ozone, and lightning also can make oxygen into ozone. Ozone formation, the ozone more density than oxygen, would gradually from the depletion of the ozone layer top to the bottom of the ozone layer falls, ozone in decline process with the temperature rise and enhance activity, and longwave ultraviolet under the irradiation of reductive become oxygen and to the depletion of the ozone layer top rise. Those who rise to the top of the ozone layer, oxygen molecules again in short wave ultraviolet under the irradiation of again decomposition into combinations ozone. Ozone and oxygen is respectively in short wave ultraviolet and longwave ultraviolet irradiation, under from high to low again from low to high cycle on the transformation, and maintain the ozone layer of relatively stable. The ozone layer insulation is careless of the earth surface solar uv radiation strongly. Atmospheric ozone in the quantity and the ozone layer of ozone density, and totally depends on atmospheric oxygen content, atmospheric oxygen content increased, the ozone cargoes, also increased the ozone layer of ozone density also can increase accordingly, or conversely. 2. purification and beautify the ecological environment. Ecological productivity purify natural environment function, mainly in green plant purify air, disintegrator purify the surface environment this two respects.
(1) the green plant purification atmospheric environment. The air contains a lot of smoke and dust pollution, bacteria, etc. A year globally sulfur dioxide atmosphere as hundreds of millions of tons, and these dust on attachment serious harm human health and other biological pathogens. Green plants/have fluff even also secrete mucus, grease substances, adsorption in the air of dust and large sulfide, fluoride such harmful substances, culling air of harmful bacteria. A lot of experimental data indicate that per hectare forest annual can absorb the dust, 600 tons annually soot absorption 600 kg per hectare sulphur dioxide, YunShaLin every year can block and absorb the dust from the air 36 tons per hectare cypress woods one day &night can secrete plant sterilization grain 50 kilograms, can annihilate a lot of diphtheria, typhoid fever, diarrhea, tuberculosis and so on many kinds of bacteria.
(2) disintegrator purification ecological environment. Ecological system of scavengers, microbial, miniature heterotrophic organisms such as decomposers has feeding, digestion and decomposition, degradation animal and plant remains, animal waste organic substances, accompanied by REDOX function, and impel the organic material of chemical elements into can be plant root absorption of organic compounds, return the soil. Able to eliminate for animal and plant remains, animal waste excessive accumulation and cause environmental pollution problems, with the purification and beautify the air, water, soil, surface econological environment the powerful effects.
3. resist and contain natural disasters. Ecological system especially green vegetation, resist natural disasters functions, is human security and sustainable development capacity of household protector. Mainly embodied in the following three aspects:
= 1 \* GB2 ¢ÅPlay the biological control function. Ecological system possesses a frog, cat, snakes, beetles, pedestrian worm, spiders, including birds predator-prey harmful biological parasitoid consisting of one thing restrict one thing, one thing subduing one content of food chain. The food chain is the balance of the ecosystem self-adjustment, with effective control hazards chain ecological and animal husbandry and fishery production diseases, pests and mice and other harmful biological reproduction, restricting harmful biological hazards, reduce harm the loss of strong biological control function.
(2) stop desertification. Forests and other vegetation is blocking the typhoon, reduce sand hit and contain land desertification, desertification natural barrier. Forest canopy can make the prevailing wind direction 30 times tree height at an altitude of abate wind speed within 40 to 50 percent, can make the leeward surface tree height at an altitude of 20 times the strength in plain area wind 30%, 1 hectare medium-thick shelterbelt can make 100 hectares of farmland from hazards of sand storms, various vegetation densely deep pierced nets, can tighten root surface sediment, can make the sediment rainfall, reduce 94%. Forests and other vegetation is defense dust storm, prevent soil erosion, contain a natural barrier, land desertification is to protect forests, grasslands, farmland, village of natural umbrella.
(3) contain natural disasters. Green plants and vegetation is the natural environmental hero, for containment and alleviate droughts, floods, dust storm, typhoon natural disasters and mudslides, mountain HuaBo geological hazards, such as an irreplaceable role. In rainfall, vegetation crown branches can intercept 65% of raindrops directly eroded surface, The residual branch leaves and roots, dense can absorb rain, like a sponge as 1 hectare forest can increase the surface water storage 300 tons, the surface the stored moisture Juan flow formed by slow deposition, and set Juan flow as the streams, rivers, streams for collection for the downstream of farmland provide irrigation water. Woodlands for flood peak impoundment function suppression and contain flooding, extend runoff in the dry season, increase water richful during the time of runoff, displays the formidable "cutting flood fill withered" regulatory function. In the sunny weather or drought, forest and vegetation and may hide barrier of the sun to avoid direct sunlight surface, reduce surface water transpiration. The roots of the forest and vegetation is fastening, prevent floods and landslides elongate-shaped HuaBo geological hazards, such as function.
D, Ecological productivity by the barbaric strangling
In ravaged ecology, resource, trample environment frivol deformity of industrial civilization, driven by nearly 50 years, especially in the global population soared cause of ecosystem and nature over extorting from, disorder request and brutal request, utterly disrupt the ecological system of food chain and balance chain, greatly cut the ecological system of biological stock, species, and biological density, ecological quantity scale and biological yield, severely weakened ecosystem vitality, productivity and balance, ecological productivity by the barbaric strangling.
(a) severe environmental pollution, ecological faced a serious threat
Global ecological environment pollution has lit up the red light, industrial emissions of solid content, waste water and waste gas, waste heat, radiological and living garbage, pesticide, fertilizer, feed the serious pollution. Comprehensive environmental pollution has throughout the earth's surface and space, land and sea, surface and underground. Has made the big empty and boundless sea, the vast land, deep crust are hard "includes", not "digest" and the earth has become almost a trash can. Especially global used annually to 6000 tons of pesticides, 200 million tons of fertilizer, including more than two-thirds of the residue will with rivers runoff into the ocean. Every year frequent offshore drilling accidental leakage, oil spill, blowout and tanker struck the collision, leaking accident caused hundreds on, oil and petroleum products each year leakage millions tons, but also increased the disastrous Marine pollution. Global atmospheric pollution, Marine pollution, land pollution, water pollution, farmland pollution has become a whole flood of power. Global greenhouse effect, the ozone layer subsidise, el nino and la Nina intensifies, polar melting glaciers, permafrost melt, rising sea levels, flood, drought, vegetation to dissipate and lasting land bare, soil erosion, desertification phenomenon is overall intensified. The entire ecosystem is already ulterly changed, black and blue, qi wounded.
(b) the ecological atrophy ecological productivity decline
In 50 years of global population explosive growth and human over extorting from, disorder solicit, savage, obtain trample serious biological and ecological system atrophy, ecological productivity serious recession. 1. biological species declined. Due to human activity occupy, predatory natural biological habitat, particularly extensive use of pesticide and fertilizer damage and human reckless disorderly and killing on the earth, biological species extinction is nowdeclining at the speed of 27,000 species disappear. Since the cretaceous the extinction of the dinosaurs, earth extinction since the peak, including birds destroyed 54%, butterfly destroyed 71%, Marine fish stock decreased 50% biological, especially large Marine creatures have been destroyed by 90%. 2. forest ecological atrophy productivity decline. Global forest area by 4.73 billion hectares reduced to present 38.7 million hectares, net reduction 8.61 million hectares, reduced 18.2%. At present, the forest area at an annual 1300 million hectares of scale is degressive. Cause forest ecological scale atrophy, biological yield, live the forest reserves serious decline, forest ecological of carbon, making the oxygen, service and other ecological productivity serious recession. 3. grassland ecological atrophy yields. Global desertification spread has devoured the grassland area of 4 million hectares, accounting for original grassland area 38.3 billion hectares of 10.44%. At present, the grassland desertification at an annual 700 million hectares of speed spread. Global grasslands grass yield per unit area than 50 years ago, a 50 percent decline in global steppe of biological yield and carbon, making the oxygen and other ecological productivity has fallen by 60%. 4.cultivated land area per capita plummeted fertility dropped. Global have 0.5 million hectares of farmland covered by desertification and industrial construction, urban construction, highway and railway construction, rural builds a house, new repair water conservancy construction projects about 0.2 million hectares of arable land, reducing global 0.7 million hectares. Plus population growth factors, global cultivated land per capita possession by 50 years ago 7.5 mu reduced to current 3.14 mu, cultivated land per capita area reduction by 58%. Global had 3.8 million hectares of land is under desertification threats, including 4 million hectares of arable land. The cultivated serious soil erosion, seldom sowing leguminous biological fertilizer, straw counters-field decrease, use organic fertilizers plummeted, cultivated land of organic fertility dropped significantly, farmland ecological productivity serious decline. 5. Marine biological stock reducing productivity decline. Global Marine planktonic seaweed biological yield only 500 million tons in 50 years ago, with less than 50%, only in the past decade is reduced by 30%, the floating seaweed death and direct to bring "occupation", coral disease caused coral become white and massive death, 30 years global coral biological yield decreased by 20%. Global coastal coastal beach, the coastal wetland, offshore coral reefs, mangrove forest area, in turn than 50 years ago cut the 40 to 50 percent. Marine fishing yield after since the 20th century using satellite technology to develop after LveDuoShi fishing, global fishing output from the 1950s in 2000 tons of fishing amount raised to 1993 1.01 million tons of the peak, then gradually declined to present year fishing amount 70 million tons of level. Due to the fishing ability greatly exceed Marine biological reproduction capacity, in 2007, global Marine fish of biological resources stock reduced by 50%, many species in endangered state. Marine fishery resources is serious exhaustion, Marine ecology of carbon, making the oxygen, adjusting the climate and other ecological productivity serious decline. Meanwhile, on the land of wetland, freshwater, alpine meadows, desert, DengZi ecosystem, because the tundra environment pollution, drought, wind and sand, desert, soil erosion, flood, hot cold natural disasters, snuggling generally present species disappear, biological stock plummeted, biological yield value-another, ecological disorders, ecological productivity decline atrophy situation.
(c) food chain rupture biological control function decline
Because of the frog, snakes, birds and other major beneficial biological stock plunged, ecosystem lost one content restrict one content of food chain and subduing one thing, one thing the ecological balance of chain, entire ecosystem has become food chain rupture of disorder, balance chain disorder failure, the ecological structure deformity, material circulation breakers of sub-health state. Ecological system ecological service function and biological control functions are big discounts, bacteria, pests and mice and other harmful organisms with the loss of natural enemies restriction and reproductive exuberant, harm rampant, serious flooding. Global of farming, forestry, animal husbandry, sideline production and fishery production have to rely on extensive use of chemical and chemical fertilizers to continue their present programme. Form lots of pesticide and fertilizer, using biological, serious injury beneficial accelerated extinction, interrupt food chain, disrupting balance chain, weaken the ecological service function and biological control function of the vicious circle. Harmful biological harm agriculture, forestry, animal husbandry, sideline production and fishery production losses increasingly serious, it is estimated that the global every year because of diseases, pests, pest damage grain output reaches 6 million tons, making up about 25 percent of the global total grain output in China, which is equivalent to the total 1.15 times.
(e) the ecological balance chain failure frequent natural calamities turf
As the world population of the explosive growth of mankind for the grain, and cultivated land, bamboo wooden material, forage and on biological resources and mineral resources in the demand of assault growth, plus deformity of industrial civilization, human and propensity reckless plundering ecological resources, leading to forest and grassland, Marine ecology system of biological stock serious atrophy, vigor degradation, especially before the more than 10 billion years photosynthesis have materialized, solid carbon and accumulated by burning the way to carbon dioxide and carbon monoxide composition, and constantly improve the return atmosphere atmospheric co2 concentration, aggravate the greenhouse effect, the ozone layer subsidise, el nino and la Nina weather activity worse. Give the earth bring in a grave ecological catastrophe. Lead to global land desertification, soil erosion, rivers and lakes choke, ecological environment seriously deteriorating. Induce underway, tornado, sandstorm, hail, acid rain, offshore red tides, drought DaLao, alpine hot extreme sexual meteorological disasters and mudslides, mountain HuaBo major geological disasters, causing a significant life and property losses.
E, to speed up the development of ecological productivity
(a) profound understanding of developing ecological productivity fundamental way
Humans from the realm of necessity to the free kingdom is relative, and humans can never get rid thoroughly the survival of nature's objective restriction, Humans from the realm of necessity to the free kingdom forever is conditional, and mankind only consciously respect and follow the ecosystem and natural evolution of the development of natural laws, to steady strides in the free kingdom of heaven. Otherwise, once the human nature for demand beyond the capacity, humans are forced to implement ravaged and destroy mybrothers ecology, waste and wasted resources, environmental pollution and trampled the malformation of development mode, and will be returned to the realm of necessity, suffered from nature and the laws of nature to severely punish, the human capacity for sustainable development also will therefore were greatly weakened.
In current and future times, biological and ecological system, ecological productivity and the human capacity for sustainable development, facing the greatest threat to mankind is excessive demand, obtain and savage disorder on request. Therefore, to correct understanding and properly handle the good man and other creatures, human and ecological system, the relationship between man and nature, the promotion of human and seek to obtain demand means and ecology, resource, environment capacity balance coordination, is human to protect and construction of ecological system, protection and development of ecological productivity, enhance human sustainable development capacity of sustainablely.

Improve development ecology and ecological productivity the pertinence, systematic and scientific and effectiveness, and promote the global ecosystem and ecological productivity recovery, evolution and development.
2.recovery and development land ecological productivity. Terrestrial ecosystem is the biological most species, biodiversity most widely, biological species distribution is most crowded, since birth, recovery, and evolutionary development ability is the strongest, the most powerful photosynthesis, unit biological highest yield and production with human life most closely related ecosystems. Development land ecological productivity, is the development of key and the whole ecological productivity key.
(1) to establish and improve global protection forest ecological international conventions, according to law, protect the global forest. Through to establish and perfect a limit wood international trade greatly improve wood tariffs, banned imports of forest area to reduce state of wood and wood products such as tough international convention effectively commercial cutting of forest ecological destruction.
(2) to protect forest ecological into curb global carbon emissions control system. Every country increase or decrease forest area as increase or decrease the main index into carbon emissions of evaluation system, and participate in carbon emissions trading, let business of deforestation countries the loss outweights the gain, Let afforestation increase the country won the forest area reduction of economic compensation. Using economic means strictly control the behavior of deforestation, enhance countries protect forests and reforestation enthusiasm.
(3) vigorously afforestation. The UN qualified international organizations, especially international charity and the developed countries, to open up the international aid, poverty relief, charity and relief activities of key, transferred to AIDS afforestation and build vegetation, construction of ecological civilization based project, in global embarking on a persistent afforestation climax, especially to the poorest countries or regions behind multiplied broad-leaved forest, mill, forests, fuel forests, GuoMuLin and forage, widely build farmland, grassland shelter forest and urban greening Lin, accelerate the plains and urban afforestation and do not bare mountain, the plain have windbreak barrier. Through the construction of ecological civilization, help curb desertification, fundamentally eliminate poverty and hunger phenomenon.
(4) the readjustment of industrial structure, the scientific planning terrestrial ecological layout. Must follow the objective law, scientific adjustment forestry, animal husbandry, agricultural industry structure, and the implementation of ecological immigrant, adjust measures to local conditions, restoration of returning farmland to forestry or pasture refund return grass, grass returning important strategic measures, achieves the appropriate grass is grass, YiLinZeLin, promote terrestrial ecosystems exuberant. To strictly prohibited in surface water added loss of perennial drought region depend entirely on groundwater over-exploitation of farming, avoid groundwater behavior brings endless drop caused by existing vegetation surface drought, withered huang, increase afforestation, grass-planting survived the difficulty of vicious circle phenomenon.
= 5 \* GB2 ¢ÉChange development pattern, the scientific development terrestrial ecosystems
1) greatly extend forest right all deadlines and pasture contracting term. To implement woodland and grassland state or collective all system country, to put all the time limit and forest pastures contracting term extended to 100 years. Flipping "only KanShuRen, disappear trees found people" and "see graziers grass-planting, disappear protects the passive state election".
2) strengthening farmland, grassland YuanTianHua shelter forest construction curb the sand to invade. Plain region upland and all grasslands are to build shelter-forest, according to prevent desertification spread, facilitate mechanized farming request, according to every 50 meters to 100 meters to build a road, and with highway roads respectively in parallel multiple lines poplar trees planted or other appropriate mill, constructing criss-cross of tree belts, in farmland, grassland props up a complete coverage of ecological shelter.
3) the full implementation of the animal husbandry and captive. Increasing grassland ungrazing, Hugh animal husbandry dynamics, promote grassland ecological restoration, improve the grassland biological yield, the development of grassland ecological productivity.
4) the development of ecological agriculture to improve soil fertility. To ZiYunYing etc comprehensive promotion farmland sowing legume biological fertilizer, increases straw counters-field, inncrease organic fertilizers to improve soil organic fertility.
(6)protection terrestrial ecological scale. All countries should reasonable planning industrial construction, urban construction, highway and railway construction, rural house sites. Pay attention to concentrated industrial production, urban construction upwards, should notice to dismantle old rural building new prevent "hollow village" phenomenon, highway and railway construction should notice to transform backlog, bridge, minimize diverted tunnel occupy farmland, forest, grassland area. International society and the developed countries to be generous support desertification serious countries and regions, scientific and efficient management and curb desertification trend, fundamentally protect and increase terrestrial ecological area, accelerate the development of terrestrial ecological productivity.
(7) defend the forest fire. By strengthening propaganda education, strengthen preventing management and ecological emigration, strengthen professional fire team construction, improve the fire-fighting equipment and consummation of air monitoring and prediction system and other measures to defend forest fires, stop the fire hazards.
3. recovery and development of Marine ecosystem, and develop the Marine ecological productivity. Should make full use of Marine ecosystem largest area and development potential, the biggest advantage of effective protection and restoration of biological species of Marine ecology, biological density, the food chain, and increase Marine biological yield, accelerate the development of ocean ecological productivity.
(1) the control Marine environmental pollution. Marine environmental pollution is lead to the Marine ecological productivity decline the culprit, and develop the Marine ecological productivity is the key to management and curb Marine pollution.
