江河源区生态系统服务价值评估初探——以江西东江源区为例

Ecosystem services and their economic values on the Riverhead Area of East River

应用生态学、生态经济学、福利经济学方法和前人的研究成果,在研究江河源区生态系统价值评估流程和评估方法的基础上,以江西东江源区为研究案例,初步估算出东江源区生态系统服务功能经济总价值为81．0亿元,约为东江源区2004年国内生产总值(GDP)的4．11倍,单位面积生态系统服务功能价值为23121元/hm^2,并对估算结果进行了分析．

In this paper, based on the general study on the values estimation flow and the values estimation methods of the Riverhead Area Ecosystem, and based on cases of the natural and social-economic characters of the Riverhead Area of East River and results of Costanza et al. , the methods of ecological economics, welfare economics and ecology were applied to analyze the economic values on the Riverhead Area of East River. The results showed that the total values of the ecosystem services were 81 ×10^8yuan, and it was 4.11 times as the GDP of the River- head Area of East River in 2004. At the same time, the estimated results are analysed.
