摘　　要：建立合理的生态补偿机制对协调区域发展具有重要意义。以宁夏南部泾源县为研究对象,利用RS和GIS相关技术分析泾源县2003年、2007年和2011年三期TM遥感影像图,解译研究区三期的土地利用变化。采用改进的生态足迹"省公顷"模型,结合宁夏平均生产力计算了适合于研究区的均衡因子和产量因子,得出泾源县生态盈余在时间上的分异特征,以2011年生态足迹效率为基准,综合农业生态足迹效率补偿、直接受益损失补偿和生态盈余动态评价补偿,对泾源县生态补偿进行定量分析。研究表明:泾源县自2003年后,土地利用变化主要集中在牧草地、林地和建设用地。2003年、2007年和2011年泾源县的人均生态盈余分别为-0.248hm2,0.159hm2和1.580hm2。较为合适的补偿标准为:年户均补偿9 669元,年人均补偿2 627元,生态补偿总额为26 610万元。研究结果以期为泾源县经济、社会、生态全面可持续发展提供参考。It＇s significant to create a reasonable ecological compensation system to promote the sustainable de velopment of Jingyuan County in Ningxia Hui Autonomous Region. The land-use change of Jingyuan County was analyzed by using RS and GIS relevant technical to analysis TM remote sensing image map in 2003, 2007, 2011. The ecological surplus characteristics in different time of Jingyuan County were obtained by ap- plying provincial hectare model, combined with the average productivity of Ningxia Hui Autonomous Region and calculating appropriate equilibrium factor and yield factor. As 2011 ecological footprint efficiency for ref- erence, comprehensive directly benefit compensation and ecological surplus dynamic compensation were quan- titatively analyzed. Results showed that the land-use change concentrated comparatively on grassland, forest- land and construction land since year of 2003. Per capita ecological surplus were improved from --0. 248 hm2 to 1.58 hm2 , the reasonable ecological compensation was 1 446 Yuan per household or 393 Yuan per capital, the total ecological compensation was 3 980. 12 million. Our target was to provide a reasonable guide and model for ecological compensation and land use, at the same time, promote economic, social, ecological sustainable development.
