摘要:

通过对太湖流域重污染区1999年、2007年遥感影像数据解译结果的分析,获取了太湖流域重污染区主要土地利用类型的信息,分析了8 a来研究区内土地利用与覆被变化趋势,对区域土地利用类型的生态系统服务价值进行评估。结果表明, 1999~2007年,太湖流域重污染区内耕地面积从2 033.53 km2减少到1 401.04 km2,而林地、建设用地、园地、水域总体呈增加的趋势,其中减少的耕地主要转化为建设用地。1999~2007年太湖流域重污染区的生态系统服务价值呈减少趋势,土地利用变化使研究区生态资产减少了2.40亿元,除气体调节和原材料以外,各单项服务功能的价值量均呈现递减的趋势。

Abstract:

Change trends of land use/cover change (LUCC) in heavy polluted area of Taihu Lake Basin were analyzed based on remote sensing image from 1999 to 2007. Ecosystem service dynamic of these land use/cover was investigated. The results show that cultivated land area in study area decreased from 2 033.53km2 in 1999 to 1 401.04 km2 in 2007, while the area of forest land, construction land and water increased. Reducing cultivated land converted to construction land. Ecosystem service of heavy polluted area in Taihu Lake Basin decreased from 1999 to 2007 and the total ecosystem services value in study area decreased 2.4×108yuan. Value of different ecosystem service item presented decreased trend excluding gas regulation and raw materials.

Key words: land use, heavy polluted area of Taihu Lake Basin, remote sensing, ecosystem services value
