摘要
以1997年和2007年LandsatTM影像解译数据为基础,根据Costanza、谢高地等人对全球生态系统服务价值的测算方法,分析了邯郸市土地利用/覆盖变化及其所引起的区域生态系统服务价值的变化。结果表明:(1)1997-2007年研究区的土地利用变化十分明显,其中耕地面积减少了414.90km2,林地面积增加了644.33km2,草地面积减少了602.51km2,建设用地增加了252.37km2,水域减少了121.99km2,未利用地增加了178.81km2;(2)区域生态系统服务价值在1997-2007年10a间呈下降态势,根据Costanza、谢高地、段瑞娟等提出的生态系统服务价值系数计算分别下降了1.2,9.7,27.1亿元,生态环境质量下降,处于不可持续发展状态。
Based on the data of Landset TM in 1997 and 2007,the artical analyzed the changes in land use and ecosystem service values using Costanzas,Xiegaodi and Duanruijuan＇ method of evaluating the global ecosystem service value.The results indicate that（1） The variation of land-use in the study area from 1997 to 2007 is dramatic,for example,the cropland decreases dramatically and reduces 414.90 km2,the area of grassland reduces 602.51 km2,froestland increase 644.33 km2,constructionland increases 252.37 km2;（2）The trend of regional ecosystem services value from 1997 to 2007 decreases 1.2,9.7,27.1 billion yuan according to the three indices,the region is under an unsustainable status.
