| 摘 要： | 以TM遥感影像为数据源,运用ERDAS9.0和ARCGIS9.0软件,采用TGDVI植被指数结合像元二分法模型测算色季拉山区鲁朗河流域1987、1999和2008年3个时期的植被覆盖度,并在此基础上,求得研究区不同植被覆盖等级的变化转移矩阵,揭示该区域21a来植被覆盖等级时空变化的过程和趋势,为研究区域提供大、中尺度植被覆盖度时空变化的基础数据。

| Abstract: | With the experimental data of Landsat TM remote sensing images and the ERDAS9.0 and ARCGIS9.0 software,the vegetation coverage in Lulang River Valley of the Sejila Mountain in 1987,1999 and 2008 were modeled by the method of TGDVI vegetation index and the dimidiate Pixel mode in Tibet,China.On the basis of this method,the change matrix of vegetation coverage grade,the spatial-temporal patterns of the change in vegetation coverage and its driving processes during this period were also discussed for providing the data of vegetation coverage estimation in Tibet. |
