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。
Using ArcGIS 9.2 and ERDAS 9.1 software platform and eco-economic method, this paper uses Costanza ecosystem service value formula and the unit value of terrestrial ecosystem services in China to discuss the land use and ecosystem services in the middle of Shule River from 1990 to 2010 Value change characteristics. The results showed that in 1990-2010, the land use in the middle Shule River was dominated by unused land, pasture land and cultivated land, accounting for 98.2% of the total area of the study area. There was no significant change in the overall land use characteristics in 20 years. The main land use changes in the middle reaches of the Shule River took place in cultivated land, construction land and pasture land. The dynamic changes of land use were 13.6%, 8.0% and 7.7% respectively. The ecosystem service value generally showed an upward trend, increasing from 34.485 billion yuan to 48.511 billion yuan Yuan, grassland and water area contributed the most to ecosystem service value of the study area. The development of eco-economy in the study area has been on the edge of a low level of coordination and ecological environmental protection needs to be strengthened.
