近十年来江苏省农用地变化特征研究

Research on the Change of Agricultural Land-using and its Characteristics in Jiangsu Province during the latest 10 Years

利用RS、GIS技术对江苏省1993和2003年两时相的TM影像进行遥感解译,研究了不同地区的土地利用变化及特征。结果表明:农用地是江苏省土地利用构成的主体,10年间该省耕地、牧草地和未利用土地面积分别减少13.1%、49.0%和86.9%,建设用地、园林地和水域面积分别增加50.1%、46.3%和6.9%。此外,江苏省土地利用变化具有明显的地域差异。对农用地变化的原因进行了简要分析。
