中文摘要	生态系统服务功能是生态学、生态经济学研究的热点问题,它与水土保持、生态环境质量、土地利用等有着密切的联系.借助于1:10万地形图、TM遥感资料和GIS方法,根据研究区的区域特点,将Costanza等人的研究与国内相关研究结合建立价值模型对艾比湖沿岸的博乐、精河绿洲进行不同历史时期生态系统服务功能价值测评.获知研究区总价值:1979年为8.52108$;1991年为7.71108$;1999年为8.13*108$.进而分析了近20 a来艾比湖沿岸绿洲的生态系统价值及其演变,探明了其价值的演变趋势,并对其变化的原因做了讨论.研究表明,研究区近20 a的生态系统服务功能价值基本上以1991年为界,呈衰减-略上升的下凹曲线变化趋势.
英文摘要	The area near Ebinur lake has become one of the deteriorating area in the Western China. The evolution of ecosystem services value was researched in the past 20 years in this area and the causes also were discussed. Ac-cording to the ecological character of the research area, the research in China, and the research of Costanza were combined to build the estimating mode. Based on the multi-temporal remotely sensed data of TM, Geographical Information System(GIS), and the estimating mode, the value of ecosystem services were estimated in Bole-Jinghe oasis of Ebinur basin. The total value of the research area is: 85 209.14 X 104 $ in 1979, 77 147. 02 X 104 $ in 1991 and 81291.66 X 104 $ in 1999. The trend of evolution of the value of ecosystem services was that 1991 was the round turning point year, and the value was decreasing from 1979 to 1991 and straightening up from 1991 to 1999, showing just a sunken curve.
