%X Taking Baigezhuang Village in Pinggu County,Beijing City as an example,the types and characteristics of land use ecosystem in 2002 were analyzed and the ecosystem service values including food production,CO_2 fixation,O_2 release, water circulation,residues treatment and recreation were calculated.The results show that the total value of(ecosystem) services is 17.0662 million yuan RMB, and approximately equals the total earning of village economy.The service value of CO_2 fixation is the biggest,accounting for 72.57%,and the next is the service value of O_2 release,accoun-ting for 15.30%.The service value of food production only accounts for 12.77% of the total service value.The service values of water supply and recreation are very small,and the service value of waste treatment is negative.
