以张掖绿洲为研究区域,在Costanza等对全球生态系统服务功能进行价值核算的基础上,结合谢高地等人的研究成果,分析了张掖绿洲1985～2006年在土地利用/覆盖变化驱动下的生态系统服务价值变化.结果表明,研究区内生态系统服务总价值呈增加趋势,21年间增加了2.96亿元,主要是由耕地面积增加和区域价值修正造成的;生态系统单项服务功能价值中废物处理的生态服务价值最高,且在研究期间内增量最大,为0.53亿元.

Based on global ecosystem service value computing formula put forward by Costanza et al and modified results proposed by Xie Gao-di et al,the ecosystem service value changes under the land use/cover change in Zhangye oasis were analyzed.The results showed that the ecosystem service value increased by 296 million RMB from 1985 to 2006,chiefly due to the area increase of farmland and regional value revision.Among the contributions of various ecosystem functions to the ecosystem service value,the value of waste disposal was the highest and increased mostly,whose increment was 53 million RMB in the period between 1985 and 2006.
