摘　　要：利用ArcGIS 9.2和ERDAS 9.1软件平台和生态经济学方法,采用Costanza等生态系统服务价值计算公式,结合中国陆地生态系统服务单位面积价值,探讨了疏勒河中游1990—2010年土地利用和生态系统服务价值变化特征。结果表明:1990—2010年,疏勒河中游土地利用以未利用地、牧草地、耕地为主,三者面积占研究区总面积的98.2%,20年间土地利用整体特征并未发生重大变化;疏勒河中游主要土地利用变化发生在耕地、建设用地和牧草地,土地利用动态度分别为13.6%、8.0%和7.7%;生态系统服务价值总体呈上升趋势,从344.85亿元增加到485.11亿元,牧草地和水域对研究区总体生态系统服务价值的贡献率最大。研究区生态经济的发展已经处于低度协调水平的边缘,需要加强生态环境保护力度。This paper studied characteristics of land use change and ecosystem services value in the middle reach of Shulehe River in 1990-2010, based on ecological economics theory and by using ArcGIS 9.2 and ERDAS 9.1 software and the calculation formula of Costanza et al. , in combination with the China terrestrial ecosystems services value per unit area. In 1990-2010, the dominant land use types in the study area were unused land, grassland, and cultivated land, occupying 98.2% of the total, and the overall land use characteristics had no significant change. The land use change mainly occurred in cultivated land, built-up land, and grassland, and the dynamic degree was 13.6%, 8.0%, and 7.7%, respectively. The ecosystem services value presented an increasing trend, from 344. 85 billion ~uan increased to 485.11 billion Yuan. Grassland and water area contributed most to the total ecological services value. The ecological and economic development in the study area was at the margin of low level coordination, and thus, protection efforts on the ecological environment should be further enhanced.
