    摘要:

    以伊犁河流域为研究对象,运用GIS手段和生态经济学方法,采用Costanza生态系统服务价值计算公式,参照谢高地等人的中国陆地生态系统服务单位面积价值,结合敏感度分析,探讨了伊犁河流域1985-2005年土地利用和生态系统服务价值的变化特征。研究结果表明:1985-2005年间伊犁河流域土地利用处于发展阶段,土地利用程度呈增大趋势。研究期内生态系统服务价值总体有所上升,从482.83×108元上升到506.44×108元,增加了23.61×108元:水域和耕地对研究区总体服务功能变化的贡献率最大,而牧草地生态服务功能的下降对研究区总体生态服务功能的增加具有较大负贡献。研究区生态经济的发展已处于协调水平的边缘,需要加强对生态环境的保护力度。

    Abstract:

    By the GIS and ecological economy theory, based on the Costanza method and the Chinese land ecosystem services unit area value proposed by Xie Gaodi, and combined with the sensitivity coefficient analysis, this paper analyzed the variation features of land use change and ecological services value in the Ili River Basin during 1985-2005. Results show that the land use in the Ili River Basin was at its developing stage from 1985 to 2005. The magnitude of land use exhibited an increasing trend, and meanwhile the ecological services value, from 482.83×108 Yuan to 506.44×108 Yuan, also showed an increasing trend. Water area and farmland contributed to the overall increasing eco-services change dominantly, while the decreased grassland eco-services contributed to it negatively. The development of eco-economy in the Ili River Basin has been on the verge of incoordination. The ecological environmental protection should be further enhanced.
