中文摘要：

基于1991、2002与2008年卫星遥感资料,采用中国陆地生态系统的服务价值测算方法,分析克里雅绿洲土地利用变化对生态系统服务价值与结构的影响。研究表明：①研究区生态服务价值从1991年的144 224.8万元降到2008年的128 716.3万元,生态服务价值损失10.8%,每年净损失生态服务价值达24.2元/hm2。生态服务总价值的减少主要是由湿地、水域总面积的减少而导致的;②研究区各生态服务功能对区域总生态服务价值贡献率由高到低依次为：废物处理、土壤形成、生物多样性保护、水源涵养、气候调价、气体调价、食物生产、娱乐休闲和原材料;③研究区生态服务价值对生态服务功能指数缺乏弹性。

英文摘要：

The effects of land use change on ecosystem services values and functions of Keriya Oasis in 1991-2008 were analyzed based on TM image data in 1991, 2002 and 2008, and using the evaluation methods of terrestrial ecosystem services value of China. Results showed that： 1） The total value of ecosystem services decreased from 1 442.248 million Yuan in 1991 to 1 287.163 million Yuan in 2008, the loss of total ecosystem service value was 10.8%, and net loss of yearly ecosystem service value was about 24.2 Yuan per hectare. The main causes of the decline of total ecosystem service value were the decrease of the total area of wetland and water body; 2） The overall rank order for each ecosystem function based on their contributions to overall val- ue of ecosystem services was that the contribution of waste treatment function is the highest, then the soil for- mation, biodiversity protection, water supply, climate regulation, gas regulation, food production, the contribu- tion of recreation and culture and raw material is the lowest; 3） The total ecosystem services value was relative- ly inelastic to the value coefficients, therefore, the estimation in this study area was robust in spite of uncertain- ties on the value coefficients.
