| 摘 要： | 本研究对以DEM生成的黄河源头范围内的土地覆被变化进行了分析，得到20世纪70年代中后期至80年代末、80年代末至2004年和2004-2008年土地覆被变化数据。同时利用转移矩阵的方法，定量研究了近30年黄河源头土地覆被类型转移的途径和幅度；分析了3个时段内的土地覆被状况指数和土地覆被转类指数，藉此探讨黄河源头不同土...

| Abstract: | Research on land cover change with different definition of the Yellow River headwaters region is of great significance.But there was no unified definition of the Yellow River headwaters region.Different definition made different result.The land cover condition in the Yellow River headwaters region derived from Digital Elevation Model(DEM) was adopted to explore its changes during three periods,i.e.1970s to late 1980s,late 1980s to 2004 and 2004 to 2008.The outlet of watershed used in this paper was Jimai hy... |
