【摘要】 以昆明市松花坝水源保护区为典型区,选取1992年、2001年两期的遥感影像资料对该地区土地利用的时空变化进行了研究。采用监督分类方法对研究区土地利用类型进行分类,发现从1982—2001年林地面积呈明显减少趋势。最后进行驱动力分析,为今后该区的水源地保护提供指导。更多还原

【Abstract】 This article researched spatio-temporal changes and analyzed the land-use of the protected district of resources of water at Songhuaba,Kunming City by selecting 1992,in 2001 two issue of remote sensing images.By using the supervised to classify land use type of this district,from 1982 to 1992 to 2001,it was discovered the forest areas reducing.Finally,it carried on the driving influence analysis and provided the instruction for this area water source protection in the future.更多还原
