| 摘 要： | 该文选取云南省临沧市为研究区域，利用2001—2015年MODIS中国植被指数合成产品Tiff遥感影像对临沧市植被覆盖进行分析。研究通过arcgis软件对遥感图像进行分析统计，汇总得研究区内15年各月的植被归一化指数，并对植被归一化指数的月、季和年变化进行分析，得出临沧市植被覆盖的变化趋势。而后，通过对比研究区数字高程影像与夜间灯光指数探索出临沧市植被分布存在的区域分布特征。同时，通过对行政区分区统计得出临沧市各区县植被归一化指数值，并结合其产业与社会状况进行分析。

| Abstract: | Lincang city of Yunnan province was selected as the research area.The Tiff remote sensing images synthesized by MODIS China vegetation index from 2001 to 2015 were used.The images were subdivided and statistically analyzed by arcgis software.By analyzing the monthly，seasonal and annual changes of the vegetation normalization index，the variation trend of vegetation cover in Lincang city was obtained.Then，by comparing digital elevation image and night light index in the study area，it was found that the distribution of vegetation in Lincang city has certain distribution rules.Based on the regional statistics of Lincang city，the normalized vegetation index of each district and county was obtained，and the correlation analysis was made with industrial and social conditions. |
