Abstract  

In this study, we mainly investigated the area along the Mainstream of the Tarim River, because of the fragility of the ecological environment and the high pressure of human activity in this region. Analysis on the feature of quantity and structure change of land utilization was done by using satellite remote sensing data in 2005-2010, the methods were based on the correction ecosystem service value (ESV) by Xie Gaodi et al. We estimated the value of the land utilizations ecology service as follows: (1) Other land-use patterns and grassland were the two principal land use types in the studied area in 2005 and 2010, with a total coverage of about 65%, the natural vegetation from 2005 to 2010 decreased to 1.04% (4.37×104 hm2), the area of farmland increased by 21.70%, the high coverage grassland land decreased by 5.95%, farmland increased at the cost of vegetation destroying and decreasing. (2)The value of soil formation, biodiversity protection and waste disposal provided by ecosystem was the highest in the studied area. The forest and water area were the main patches to constitute the ecosystem service value. As a whole, the changes of land use pattern lead to changes in the structure of the ecosystem services function in the area along the mainstream of Tarim River in 2005 and 2010. (3) The ecosystem service value in the area along the Mainstream of the Tarim River was 137.76×108 yuan (RMB) in 2005, and 137.98×108 yuan (RMB) in 2010. The ecosystem service value reduced from in the upper to lower reaches of Tarim River. The sensitivity analysis suggested that to estimate the change of regional eco logical service value was practicable and would make a reference for the evaluation of land use benefits and the organization of land use planning.

Key words:  land use change      ecological service value      sensitivity coefficient      mainstream of Tarim River
