塔里木盆地南缘克里雅绿洲土地利用变化对生态系统服务价值的影响研究

以塔里木盆地南缘克里雅绿洲作为典型区，分析1991-2001年土地利用变化对生态系统服务价值的影响。研究结果表明，克里雅绿洲在1991-2001年土地利用变化很明显，生态服务价值从1991年的10．004×10^8元降到20,01年的8．792×10。元，生态服务价值损失了12％，平均每年净损失生态服务价值32．2元／hm^2湿地生态服务价值的变化最大，变化率高达-37．54％。湿地、水体面积变化的绝对量高、生态服务功能价值指数大是导致研究区生态系统服务总价值降低的主要原因。敏感性分析结果表明，克里雅绿洲生态服务价值对生态服务功能指数是缺乏弹性的，研究结果是可信的，可为研究区土地利用规划提供借鉴。

Research on Effects of Land Use Change on Ecosystem Services Value in the Northern Tarim Basin Keriya Oasis

Keriya Oasis in northern Tarim basin was selected as a target area, the effects of land use change on eco- system services value within 1991 and 2001 was analyzed. Integrated with the current state of the study area, the money was selected as the evaluation method. The results showed that the land use pattern of study area has changed greatly within 1991 and 2001. ecosystem services value of the area decreased from 10. 004×108 Yuan in 1991 to 8. 792 ×108 Yuan in 2001, losing 12% , losing 32.2 Yuan per hm2 ecosystem services value per year. The change of ecosystem services value of wetland was the main factor that resulted in the decrease of total ecosystem services value of the target area. The analysis on the sensitive coefficient showed that the ecosystem services value is short of flexibility in the area and the result is credible, which may provide reference for land use planning for the target area.
