池州国家级生态经济示范区生态系统价值的计算

Calculation of the Eco-system Value of Chizhou Nation Demonstration Area of the Ecological Economy

利用Mark·T·Brown的自然资本能值法和Costanza的生态系统效益价值法,从经济角度分别计算了池州生态经济示范区的生态系统的资本价值和效益价值,得出该示范区生态资本可达7899亿美元,其中缓慢可更新生态资本和不可更新资本分别占24 8%和75 2%,是2001年本地区GDP值的1000倍;生态效益价值达192 3亿元人民币,是2001年本地区GDP的3 1倍,生态系统对环境贡献率大。通过价值计算进一步论证了池州生态经济示范区的生态示范作用,为充分合理地发挥生态系统效益促进经济与自然协调发展提供科学依据。

The authors calculated separately the ecosystems capital value and benefit value of Chizhou Demonstration Area of The Ecological Economy from economy,using Mark Brown method of natural capital emergy and Costanza's method of ecosystem benefit value.It got such conclusion that the ecological capital of Chizhou Demonstration Area of The Ecological Economy reached 789.9E9 dollars among which the slow renewable ecological capital and unrenewable capital made up 24.8% and 75.2%, and that the ecosystem benefit value reached 19.23E9 yean,which were seperationly 1000 times and 3.1 times as high as GDP value in this area in 2001.The ecosystem already made a great contribution to the environment.It further proved that Chizhou Demonstration Area of The Ecological Economy played an exemplary role through calculating the value,and provided scientific basis for fully and reasonably making the most of ecosystem benefit and stimulating the development harmoniously of economy and nature.
