朝阳市土地利用/覆被变化研究

随着社会的高速发展,资源与环境问题日益显著,土地利用/覆被变化(Land Use and Land Cover Change,LUCC)的研究日益成为全球范围内的研究热点。本文基于辽宁省朝阳市6期LandsatTM影像,以ENVI 4.5和ArcGIS为图像处理平台,采用决策树分类方法,将朝阳市土地利用类型分为耕地、林地、水域、建设用地、未利用地五大类,通过对比多期朝阳市土地利用的变化情况,分析研究区土地利用/覆被动态的内在变化规律,进而综合评价朝阳市土地利用效率及各类土地利用转化情况。

Research on the Land Use/Cover Change of Chaoyang City
