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
