中文摘要：

利用1996年、2003年和2008年TM影像获取土地利用数据，并运用Costanza的方法，结合谢高地修正的我国生态服务价值当量因子表，分析1996年-2008年研究区土地利用的变化，计算由此导致的生态系统服务价值及其结构的变化。1996年-2008年研究区的土地利用变化十分剧烈。草地增加的幅度最大，达66019．78hm2，未利用地减少的幅度最大，达85958．67hm2。1996年-2008年生态服务总价值呈持续增加的趋势，2008年达到最大值52．45亿元。1996年-2003年，水文调节功能价值比例上升最多，主要是由于水文调节价值系数最高的水域增加引起的。2003年-2008年，上升速度最快的是气体调节价值，主要是气体调节价值系数最高的林地增加造成的。土地利用变化使得生态系统服务价值及其结构均发生改变，从而导致整个生态系统失去平衡。因此，区域发展规划必须把生态环境保护放在重要位置。

英文摘要：

Using the data of land use change produced from the integrating Landsat TM images of Turpan City form 1996 to 2008, as well as basing on the Costanza＇ s method and the coefficients proposed by Gao - di Xie,analyze the study area＇ s changes of land use and examine their effect on the changes of ecosystem services value. The variation of land - use in the study area from 1996 to 2008 was dramatic. The lawn increased dramatically and reached 66019.78 hm2. The unused land decreased dramatically and reduced 85958.67 hm2. The ecosystem services value increased between 1996 and 2008, and reached the peak value （52.45 billion） in 2008. During 1996 -2003, the value of hydrology adjustment function rise mostly, it was mainly caused by water increasing. During the 2003 -2008, the gas conditioner value rised fastest,it was mainly caused by forest land increasing. The change of land - use made both the ecosystem services value and its restrcture change, and led ecosystems unbalance. As a result, regional developrent plan（RDP） must place prime emphasis on protecting ecological environment. Only the Turpan land utiliZation structure＇ s optimization, the oasis will have the ecological environmental.
