Abstract: Ecosystem services refers to the ecosystem goods and services, which represent the benefits that human population demand, directly and indirectly, from ecosystem functions. There are the life-support system for all of the life on the earth, and are the key natural capital of humanity. It is of great significance to estimate ecosystem services value. Continuous existence of the services of ecological systems is taken for granted, never before have human action so threatened their provision, most of them are public goods and not traded in markets, and thus resulted in the continuous decrease of ecosystem services and the deterioration of ecosystem functions that generate them. The valuation of ecosystem services has been becoming one of the focuses of sustainable development, environmental economics and ecology. Various attempts have been made to calculate the value of global and regional ecosystem services. The valuation of ecosystem services isessential to the integrated accounting of environment and economics. This paper based on the data of 1:100000 Landsat TM in the Tarim River Basin in 1986, 1990 and 2000, and analyzed the land use and land coverage changes. It is found that the land use and land cover in the Tarim River Basin has changed greatly during the past 14 a, because of human's irrational development and utilization of water resources and ecosystems. By using method proposed by Constaza et al (1997) and others, the result shows that the annual value of the ecosystem services in the Tarim River Basin was 77. 84×106$ (646.07×106 ¥RMB) in 1986; and 105.93×106$ (879. 22×106¥RMB) in 1990; and 183.77×106$ (1525.29×106 ¥RMB) in 2000.Because of the reservoir area is increased steady, the total annual increase value of the ecosystem services in the this study area. Taking into account that such ecosystems as permanent snow and glaciers, construction land, salt lick, and desert and gravel desert also have ecosystem services value, this value of the ecosystem services in the Tarim River Basin is a conservative estimation.

Key words: Tarim River Basin, ecosystem services, sustainable development
