Abstract:

The ecosystem service is the support system for us human beings and the whole life system on this planet，and it also refers to the formed qualification and maintained efficacy of the whole ecosystem for us. In this paper，based on cases of the natural and socialeconomic features 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 total value estimated of the ecosystem services is 81×108 yuan，and it is 411 times as the GDP of the riverhead area of East River in 2004. At the same time，the estimated results were analyzed. Through the research，this paper intended to explore the ecological function of riverhead area and its importance in maintaining the ecosystem service functions of the region and the watershed，so as to provide scientific basis for the ecological protection and sustainable use of resources of riverhead area，and also provide references for the research of ecosystem service value of riverhead area.

Key words: ecosystem services, economic value, riverhead area of the East River
