摘要：

论文选择西北干旱区塔里木河流域、玛纳斯河流域、石羊河流域以及黑河流域4个典型流域为研究对象,以1994年土地利用分类图、TM影像,2005年CBERS影像数据为基础,参照谢高地等提出的"中国生态系统服务价值当量因子表",在对这4个典型流域生态系统服务价格根据其消费指数以及不变价格订正的基础上,逐项估计了这4个流域农田、森林、草地以及水体生态系统各项生态系统面积、服务价值及其变化。结果表明,这4个流域提供环境保护的支撑生态系统(森林、草地、水体)面积2005年普遍小于1994年,而农田生态系统面积增加显著,并且相对于较大面积的内陆河流域,小流域内各类型生态系统面积变动比较大,变动速度相对较快;塔里木河流域生态系统服务价值最大,具有较高的稀缺性,但黑河流域生态系统服务价值的增加幅度最大,这两个流域相比,黑河流域各生态系统的服务功能对于该区域人们的生活生产更为重要,影响更直接;塔里木河流域农田生态系统面积增加幅度最大,但其区域内人们对农田生态系统服务价值支付意愿的增长速度却保持最低,这说明该区域内部人们对这种生态系统服务功能的支付意愿与其资源丰富程度并不对称,需要加强宣传水土安全保护与生态经济发展的观念。

Abstract:

Tarim River Basin, Manas River Basin, Shiyanghe River Basin and Heihe River Basin have been taken as typical regions and hot spot to study value of ecosystem services. Studies on land use/land cover changes and their landscape ecological function were carried out by GIS according to landscape ecology principles on the basis of TM in 1994 and CBERS in 2005. Price of cropland, forest, grassland and water ecosystem services in typical river basins were carried out by "equivalent weight factor of ecosystem services per hectare of ecosystems in China: combining with the Engel coefficient(household expenditure on food). It was found that the area of forest, grassland and water ecosystem decreased in large, but the area of cropland ecosystem increased intensively. Comparing the larger area of the river basin with the smaller one, area of the latter changed greatly, and the ratio of change was more quickly. The economic value of ecosystem services in Tarim River Basin was maximal, which was scarcity. The increasing extent of ecosystem services in Heihe River Basin was maximal. Comparing the Tarim River Basin with Heihe River Basin, the ecosystem services function of the latter impacted more on the lives and yield of typical population. The increasing extent of cropland ecosystem area in the Tarim River Basin was maximal, but the price of the ecosystem services value kept the lowest. It was found that the payment willingness of the population was anisomerous with the economic value of ecosystem services function in the Tarim River Basin. It was important to reinforce the sustainable development idea of environment protection and economic development.

Key words: Tarim River Basin, Manas River Basin, Shiyanghe River Basin, Heihe River Basin, payment willingness
