摘　　要：基于2006,2010年遥感影像获得的宁夏土地利用变化数据,结合RS和GIS技术,对宁夏土地利用/覆盖变化特征进行分析,并用生态服务价值方法对宁夏土地利用变化的生态效应进行综合评价.结果表明,"十一五"期间,宁夏土地利用类型发生了明显变化,林地面积大幅度增加,总体生态服务价值增加4.92×107元,年增长率为2.27%,整体生态环境指数从15.37增长到17.07,整体生态环境向着健康方向发展.Using the remotely sensed （Thematic Mapper） TM images of 2006 and 2010, the land use and land cover change （LUCC） in Ningxia Autonomous Region during the period of the Eleventh Five-year Plan were analyzed through remote sensing （RS） and Geographic Information System （GIS） technologies. The LUCC accompanying ecological effects in this period were further comprehensively evaluated by applying ecological service value method. The results showed that the land use patterns in Ningxia Autonomous Region changed significantly during the period of the Eleventh Five-year Plan （i. e. , from 2006 to 2010）, with the area of forest land increased substantially. The total ecosystem service value increased by 4.92 × 10^7 yuan, with a 2. 27% increased rate per year. The whole ecological environment index increased from 15. 37 to 17.07, which means the environmental ecological quality had improved. Overall, the ecological environment of Ningxia Autonomous Region had been developed toward healthy direction during the Eleventh Five-year Plan.
