| 摘 要： | 运用土地利用/覆被类型动态度、土地利用/覆被程度模型和生态系统服务价值估算模型,分析了新疆焉耆盆地1990—2011年LUCC变化引起的生态系统服务价值的变化。结果表明:(1)在1990—2011年,焉耆盆地水域、湿地、沙地、耕地和建设用地均呈增加趋势,而盐碱地、草地和林地面积呈减少趋势,总体上研究区的土地利用程度为中下水平。(2)在1999—2011年,研究区的生态系统服务总价值总体上呈增加的趋势,其中水域和耕地对生态系统服务总价值贡献率较大,草地和林地对生态系统服务总价值有明显的负贡献。(3)在1990—2011年,研究区的各类生态系统的气候调节、水源涵养和废物处理功能的生态系统服务的总价值远远大于粮食生产和原材料供应功能的总价值。因而对区域的水土资源实行合理与有效的利用是实现焉耆盆地生态系统服务功能维持和可持续发展的关键。

| Abstract: | In this paper, we analyzed the land use/cover change and the change of the ecosystem services value in Yanqi basin in 1990-2011 by using the land use/cover type's dynamic degree, land use/cover degree model, and the ecosystem services value model. In 1990-2011, there was an increase trend in water area, wetland, sandy land, farmland and instruction land, the area of saline-alkali soil, grassland and forestland decreased. (2) The ecosystem services value increased gradually during the research period. The contribution rate of the water area and farmland to the value of the ecosystem services was large, the decreasing of the ecological service functions of grassland and forestland had negative contribution to the ecosystem services value. (3) The ecosystem services value in climate regulation, water supply and waste treatment of the different ecosystem in the research area was larger than the ecosystem services value in food production and raw materials. It indicates that the ecological service function of ecosystem is larger than its producing function in the research area. Therefore, reasonable use and effective management of water and land is the principle of the preservation and the sustainable development of the ecosystem service function. |
