Based on remote sensing data of LandsatTM and ETM + (1990,2001),using ecosystem service value coefficient of different Chinese ecosystem types published by Xie Gaodi,the land use change of Ebinur Lake region during 1990-2001 was analyzed,the ecosystem service value was calculated.The results showed that:From 1990 to 2001,the ecosystem service value of research area increased 6.537 6 × 108 yuan,and the average change rate is 1.09％.In the structure' s change of ecosystem service value,the rate of gas regulation,climate regulation,soil shape and protect,waste disposal and food produce increased,the others decreased.The estimated results are relatively reasonable by calculating the coefficient of sensitivity.%基于1990和2001年2期Landsat TM/ETM+遥感数据资料,采用谢高地等人的中国陆地生态系统单位面积生态服务价值表,分析了1990～2001年艾比湖地区土地利用动态变化,计算了其生态服务价值.结果表明:1990 ～2001年研究区生态系统总服务价值共增加了6.537 6亿元,年平均变化率为1.09％；在生态系统服务功能价值结构变化中,气体调节、气候调节、土壤形成与保护、废物处理和食物生产5个单项服务功能价值比例上升,其余的4个单项服务功能价值比例下降；敏感性分析结果表明,生态系统总服务价值对生态系统服务价值系数缺乏弹性,研究结果是可信的.
