The System For Evaluation The Economic Value Of Inland Wetland Nature Conservation

Wetland ecological system together with sea ecological system and forest ecological system makes up the three ecological systems of the earth.Particularly,wetland ecological system is also called "the earth's kidney",which is one of the indispensable ecological system in the earth.Wetland ecological system could provide the basic conditions of production,living and raw materials for regional creature. Thus,wetland ecosystem has enormous economic value.In this paper,we studies one of the protection of wetlands,namely,nature reserve of inland wetlands.Nature reserve is the most economic and effective approach of biological diversity and in situ conservation of natural heritage,and is the important guarantee of human economic sustainable development.The ecosystem in nature reserve has high integrity and stability.Thus,it could provide ecosystem services and economic support more significantly.In the nature reserves of China,nature reserve of inland wetlands has the characteristics of large number and wide area,and also has an important significance and the huge economic value.The purpose of this study is to construct the economic evaluation system of an inland wetlands nature reserve.On the basis of a summarization about the evaluation of inland ecosystem service value at home and abroad and the characteristics of inland wetlands nature reserve,the author selects economic value index of inland Wetlands nature reserve,builds the three points system of economic value evaluation on the river nature reserve with 25 indexes,lake nature reserve with 25 indexes and swamp nature reserve with 24 indexes into 4 levels(A,B,C,D).The economic evaluation ecosystem includes not only the value of wetland ecosystem but also the value of others in the inland wetland nature reserve.On the basis of Ecology,the study improves the calculation method of functional value on biological habitat by using analytic hierarchy process.Up to now,there is less research on the economic value evaluation of river nature reserve.Thus, the author selects a river nature reserve(national nature reserve of Yellow River wetland in Henan province),and calculates the value of 25 indexes in the economic evaluation system of inland wetlands nature reserve.The highest value of all indexes is 1037.78 billion yuan/year by functional value on biological habitat.The total economic value of this nature reserve is 3577.45 billion yuan/year by field survey and data collection and using the economic value index system of river nature reserve.
