| 摘 要： | 为了定量分析岷江上游地区生态系统服务功能及其价值变化,运用遥感、地理信息系统和一系列数学方法对其评估,为更好的管理生态系统提供合理化建议.结果表明：土地利用转换主要发生在森林,农田和草地之间.从1986年到1994年,农田面积增加了60801hm^2,比1986年增长了477%;林地面积减少了89012.17hm^2,占原有面积的4.97%.人口增长和森林砍伐降低了森林生态系统服务价值,相应地农田生态系统服务价值升高.生态系统总的服务价值从1986年到2000年减少了771.11亿元.本文还探讨了生态系统服务价值变化的驱动力,其中国家政策在生态系统服务功能保护上起到了一定的作用.

| Abstract: | The remote sensing (RS) and geographical information system (GIS) technologies were adopted and a mathematic method was developed
to evaluate the changes of ecosystem services in the upper reaches of Minjiang River-valley for providing advices to manage
the ecosystem. The results showed that the land use change mainly occurred on forest, farmland and grassland. From 1986 to
1994, the area of farmland increased by 477% (60801 hm2), while the area of forest decreased by 4.97% (89012.17 hm2). From 1986 to 2000, the eco-service value of forest was degressive but that of farmland increased greatly as the increasing
of planting area, while the total eco-service value decreased by 771.11×108 yuan RMB due to the rapid increase of population in this region. The driving force of eco-service change was also discussed
in the paper. The nation policy of Natural Forest Protection Project has taken effect in preventing the decline of eco-services.
