| 摘 要： | 以四川省普格县为研究区，选择2000年、2006年Landsat TM数据和1：50000地形图作为基本信息源，对遥感数据进行辐射校正、几何校正、图像裁剪处理后，计算出两期图像的归一化植被指数（NDVI），对植被覆盖度进行估算。根据结果经过对比分析表明普格县六年间植被覆盖度主要呈增高趋势，总体上认为研究区植被覆盖度变化和人类活动有不可分割的密切关系，近几年来的长江上游水土保持和退耕还林等生态建设工程在该地区已经取得一定成效。

| Abstract: | In this paper, Puge County was selected as the study area. The Landsat TM data collected in 2000 and 2006,and the 1: 50 000 topographic maps of the study area were chosen as the basic information resource. Radiation calibration, geometric correction and image cutting of remote sensing data were processed by using ENVI and ERDAS software. And the vegetation coverage was estimated by normalized difference vegetation index (NDVI). Finally, we use ARCGIS to mapping the result. After comparative analysis, the ve... |
