Study On The Typical Soil Ecosystem Services Value In Henan Province

With the development of human society and the deterioration of ecological environment,ecological research is becoming more and more deep,ecosystem services and its value has become today's academic research hot spot and front.Ecosystem services and its value of research involves different subjects such as ecology,economics,and is a complicated and systematic science.Soil is the development and origin of life,the foundation of matter and energy circulation and has a close connection to the human.Soil ecosystem is an important part of terrestrial ecosystem and its ecological services has the very high value,but most of these values for the indirect value is not directly into the market is easy to be ignored by people,So on soil ecosystem services and value of the research is of great significance,is advantageous to the soil resources rational allocation and the sustainable development of ecology,economy and society.As the first big agricultural province in China,Henan province is an important base of agricultural productions,the agricultural output ranked among the top national and strategic position is self-evident.With the development of agriculture and the pursuit of economic interests,the reclamation land clearing,the unreasonable agricultural structure,excessive application of pesticide,chemical fertilizer to the soil ecosystem bring heavy burden and destruction.But the soil ecosystem research about Henan province is lopsidedly.,research mostly focused on the production value of soil directly into the market,on the soil ecological services from its indirect value research is less.So this article on the basis of fully understand the various types of soil in henan province,based on the soil in classification,selected 9 types of typical soil in the area,yellow brown soil,yellow cinnamon soil,brown soil,cinnamon soil,skeleton soil,shajiang black soil,moisture soil,paddy soil,sandy soil as the research object,selected the service function to establish evaluation system related to soil,a preliminary calculation of typical soil ecosystem in henan province production function,the function of water conservation,nutrient cycling and service value of soil conservation function,to improve people's ecological environmental protection consciousness,construction of green GDP and the ecological compensation policy,promoting the construction of ecological civilization,to maintain the sustainable development of ecology,economy and society in henan province.The results show that:(1)Soil ecosystem services value is 79996.20 x 10~4 yuan,which value of moisture soil,cinnamon soil,skeleton soil,yellow cinnamon soil is higher,respectively are 22985.35×10~4yuan ? 13477.73×10~4yuan ? 11062.41×10~4yuan ?10891.49×10~4yuan,respectively accounted for 28%?17%?14%?14% of the total value.Sandy soil ecosystem services value of the minimum is 353.06×10~4yuan,accounting for 0.4% of the total value.(2)In henan province,typical of soil nutrient cycle in soil unit area ecosystem services value is 3249.57 yuan/hm~2,soil unit area production function value is 1794.42 yuan/hm~2,per unit area of water conservation value of 74.25 yuan/hm~2,soil conservation function value per unit area is 73.20 yuan/hm~2.Production value,the value of water conservation,soil nutrient cycling and soil conservation value were 27650.72 x 10~4 yuan,1144.13 x 10~4 yuan,50073.45 x10~4 yuan,1127.90 x 10~4 yuan,respectively 34.57%,1.53%,62.59% and 1.53% of the total value.Comparison shows that value of nutrient cycling and the production function is worth more than the value of water conservation and soil conservation value,therefore,to increase in the future research on the function of water conservation and soil conservation function research,the value of this two functions in order to improve the soil.(3)the ecosystem services value of different soil types in henan province is very different,on the one hand is due to the greater difference between the area of the soil type,which makes all kinds of soil ecosystem services value have great difference.On the other hand is because of the degree of soil disturbance from human factor is different,can be seen from the above results,the function value per unit area production type of soil and water conservation value high mostly human activities influence of soil and nutrient cycling and soil conservation value per unit area of high soil type is mostly affected by human activities of natural soil.(4)according to the study of typical soil in henan province of henan province has a great potential for soil ecosystem service function value,each type of the ecological value of the soil for the local social and economic development plays an important role,so according to different soil types,adjust measures to local conditions to improve and make use of in the protection of ecological environment at the same time guarantee the maximization of economic benefits,ecological and economic win-win.Constructing reasonable ecological compensation mechanism and policy,to promote coordinated development of ecology,economy and society,promote the sustainable development of regional ecological and economic.
