摘　　要：以新疆焉耆盆地为例,利用从1964-2007年遥感影像中获取的景观数据,分析了焉耆盆地绿洲区域土地利用变化。在此基础上,采用中国陆地生态系统服务价值的测算方法,评估了焉耆盆地绿洲区域生态服务价值并分析了景观之间的转化所引起的生态服务价值的变化。结果表明:在过去的近50年间,焉耆盆地土地利用变化趋势是以农田取代草地而发展的。绿洲区域生态服务价值总量变化不大,2007年比1964年只下降了37570万元,但各景观生态服务价值变动很大,其中农田生态服务价值增加了9.8亿元,草地的生态服务价值减少了8.8亿元,其变化率分别达到350.14%和-76.77%。各景观类型中湿地景观的生态服务价值贡献系数最大,达到3.7;其次是水域,生态服务价值贡献系数为2.71。因此,在绿洲开发建设的过程应加强对湿地和水域的保护,以实现焉耆盆地的可持续发展。Based on the data of land-use/land cover change produced from the integrating Landsat TM images of Yanqi basin from 1964 and 2007,the dynamics of the ecosystem service value was evaluated.The results showed that swamp was very important to the ecological system in Yanqi basin and its contribution coefficient to the total ecological services value was 3.7 and contribution coefficient of water landscape was 2.7.The total ecological services value was only decreased by 1000.79×104 RMB Yuan from 1964 to 2007,but ecological service values of each landscape changed greatly.As compared with other landscape types,the ecological service values of the farmland and grassland changed most greatly,and the ecological service value of farmland landscape was increased by 9.8×108 RMB Yuan and the ecological service value of grassland landscape was decreased by 8.8×108 RMB Yuan.The ratio of change was 350.14% and-76.77%.These significant changes in land-use occurred within the whole basin over the study period and causeds such severe environmental degradation problems as land degradation and vegetation degeneracy,water environmental change,etc.
