| 摘 要： | 研究土地利用背景下的生态系统服务价值变化对促进区域生态建设和可持续发展具有重要意义。以赣江上游流域为例,依据1990年、1995年、2000年和2005年4期的遥感数据,利用RS和GIS手段对土地利用数据进行了处理,并分析了土地利用变化引起的生态系统服务价值变化。结果表明,1990-1995年赣江上游流域生态系统服务价值变化不大,1995—2005年生态系统服务价值总量不断增加,且各类生态服务功能价值波动较大;各土地利用类型生态系统服务价值敏感性指数都小于1,表明生态系统服务价值对服务价值指数缺乏弹性。

| Abstract: | It is of significance to study the effect of land use change on ecosystem service values. Based on TM image data in 1990, 1995, 2000 and 2005 of the Upper Reaches of Ganjiang River, this paper analyzes the land use change and its consequent changes in ecosystem services value in the watershed from 1990 to 2005 by RS and GIS technology. The results show that the total ecological services value exhibits an increasing trend from 1990 to 2005. The total ecological services value of the upper reaches of Ganjiang River has less change from 1990 to 1995, which the total ecological services value has been continuously increasing and it is to exist the larger fluctuation in somea ecosystem function services from 1995 to 2005. The ecosystem services value sensitivity index of each land use type is less than 1, indicates that the ecosystem services value of the Upper Reaches of Ganjiang River lacks flexibility on its service value index. |
