| 摘 要： | 以MSS、TM、ETM及CBERS遥感数据为主要信息源,辅以DEM、土地利用现状图及地质图等专题数据,通过信息自动提取的方法,结合人机交互解译和野外检查验证,编制各期水土流失现状图,再利用GIS空间分析得到不同时段水土流失变化图。监测结果表明,黄河流域水土流失面积达484737.20 km^2,占整个流域的61.04%。水土流失强度变化特征是1975-2000年加重区大于减轻区,2000-2007年减轻区大于加重区。

| Abstract: | Data sources include mainly MSS,TM,ETM and CBERS,together with DEM,China's geological map,terrain map and land use map.Through automatic information extraction,naked-eye and computer aided interpretation and field work,the authors compiled the land erosion map of four stages.Erosion change information was extracted by using the technique of GIS space analysis.The statistic results show that the area of land erosion in the Yellow River Drainage Area has reached 60% of the whole area.From 1975 to 2000,the agg... |
