Abstract:

为了查明雅鲁藏布江源区的草地植被盖度,采用Landsat5TM数据,以其派生数据NDVI,RVI,VI3,PVI,DVI,MSAVI,SAVI,TM4/TM5为主要分析因子,结合野外植被样地调查数据,选取相关性最高的因子与植被盖度实测值建立回归模型,然后利用该模型反演源区的植被盖度。研究结果表明:1和其他几种遥感评价指标相比,TM4/TM5的比值与草地植被盖度的相关性最高,与草地植被盖度实测值的变化趋势一致,在光谱特征上增强了不同退化程度草地植被的光谱反射值差异,最适宜用于草地植被盖度建模;2雅鲁藏布江源区植被盖度的10个分级中,植被盖度为10%~20%的分布地区最多,面积达到4322.15km2,占全部草地面积的49.27%;其次是植被盖度为0~10%和20%~30%的地区,面积分别达到2238.53km2和1397.87km2,分别占全部草地面积的25.52%和15.94%;植被盖度高于50%的草地面积为195.96km2,仅占源区草地总面积的2.23%;3植被盖度大于50%的高覆盖度植被区主要分布于4426~4800m高程范围内,面积达到186.25km2,占整个源区高覆盖度草地面积的95.04%,这与源区的水分分布条件相关。
