摘要: 利用1990和2000年2期TM影像,对塔里木河上游典型绿洲的土地利用面积变化进行了研究,在土地利用变化背景下,通过货币化生态服务功能,揭示塔里木河上游典型绿洲生态价值的变化。研究表明,1990~2000 年研究区土地利用变化显著。农田、居民点、盐碱地大面积增加,草地、林地、水域、湿地都有不同程度的减少;10年间研究区生态价值为负增长,减少了1.055×109 元,由于土地利用变化而造成的生态价值损失巨大,而国民生产总值增加了3.652×109 元。不顾生态环境的损失,盲目追求经济的增长,最终无法实现经济与社会的最大效益。评估区域生态价值,并将其纳入区域环境与经济综合核算体系意义重大。

Abstract: Based on the TM images of 1990 and 2000,this paper analyzed the land use changes in Akesu-Awati oasis at the upper reaches of Tarim River,and,with the equivalent weight factors of ecosystem services,estimated the ecological value under these changes.The results showed that the land use changes in test area were notable,with the rapid increase of cropland,residential site and saline land,and the decrease of grassland,forest land,water area and wetland to different degree.During 1990-2000,the ecological value became negative,and decreased by 1.055×109 Yuan.There was a great loss of the economic value of ecosystem services,which meant that only through sustainable development,could we achieve the best development of society and economy in the research area.
