色季拉山区鲁朗河流域植被覆盖度遥感估算研究
Estimating the Changes of Vegetation Coverage by Remote Sensing Date in Lulang River Valley of the Sejila Mountain
摘要
Abstract
With the experimental data of Landsat TM remote sensing images and the ERDAS9. 0 and ARC-GIS9. 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, Chi-na. On the basis of this method, the change matrix of vegetation coverage grade, the spatial-temporal pat-terns 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.关键词
