摘　　要：[Objective] With the background of dramatic changes in land use patterns,the aim was to explore the ecosystem services value of Fei County based on RS and GIS.[Method] Ecological changes in the environment can bring changes in economic value expressed quantitatively by ecosystem service value （ESV）.According to modified ESV equivalency factor tables and three periods of interpreted TM remote sensing images in 1990,2000 and 2009,this paper calculated the total ESV in Fei County,Shandong Province,China and analyzed the relationship between ESV and the land-use changes at last.[Result] The results showed that the total ESV of the study area decreased from 2.144×109 yuan in 1990,2.139×109 yuan in 2000,and at last to 2.098×109 yuan in 2009 as the overall study area land use pattern changed dramatically,in which the built-up land increased by 23％,while the cropland and forest were constantly on the decrease.[Conclusion] The research provides theoretical support for the construction of high efficient ecological economic zone and sustainable development of the region.[目的]以变化剧烈的土地利用格局为背景,研究费县生态服务价值的变化。[方法]生态环境的变化同样可以带来经济价值的变化,可以用带有货币形式的生态服务价值定量计算出来。本研究以费县为研究区,依据1990,2000,2009年的TM遥感影像解译数据,运用Costanza的方法,结合修正后的我国生态服务价值当量因子表,分析了生态服务价值和土地利用变化之间的关系。[结果]研究结果显示:随着土地利用格局的剧烈变动,如城镇等建设用地不断扩张,增加了23%,对应的耕地,林地等的不断减少等等,生态服务价值呈现逐渐递减的趋势,即从1990年的2.144×109元到2000年的2.139×109元,最后到2009年的2.098×109元。[结论]为费县高效生态经济区建设和区域土地可持续利用提供了理论支持。
