以张掖市甘临高地区为研究区，基于RS和GIS分析了研究区2000-2007年的土地利用变化及其生态系统服务价值时空变化的特征，同时对生态系统价值系数和土地利用数字化过程引起的不确定性进行敏感性分析．结果表明，研究区耕地和城镇用地面积不断增加，湿地和草地资源逐渐减少；生态系统服务价值由2000年的57.44亿元下降到2007年的55.31亿元，降低幅度达到3.71％；研究区西南部的生态系统服务价值呈现出较大的变化；敏感性分析的结果均小于1，表明尽管生态系统服务价值系数和土地利用的数字化过程具有不确定性，研究结果仍然是可信的．

Taking the case of Gan-Lin-Gao district in Zhangye City , the total ecosystem service value in response to land use changes are evaluated by geographic informational system and remote sensing between 2000 and 2007 at temporal and spatial scale . Also the sensitivity analysis is conducted as to the uncertainty on ecosystem service value coefficient and area of different land use type . It is found that arable land and urban construction land expand rapidly but the wetland and grassland resources decrease gradually . And the total ecosystem service value dropped from 57.44 × 108 Yuan in 2000 to 55.31 × 108 Yuan in 2007 . The magnitude amounts to 3.71% . Areas with great changes on ecosystem service value are mainly located in southwest region in the study area . The results of sensitivity analysis are less than one ,which reveal that although there are uncertainty in ecosystem service value coefficient and the digitalization process , the results are still credible .
