利用城市夜间灯光资料和NDVI研究成都地区植被覆盖度变化
Vegetation Coverage Changes in Chengdu Based on DMSP/OLS and SPOT-VEG NDVI
摘要
Abstract
The effect of urbanization process on vegetation coverage was analyzed by using SPOT VEG NDVI and DMSP/OLS data in the Chengdu region from 1998 to 2013. The results show that:the urbanization in Chengdu experienced a continuing and rapid process, but the degree of development of each region has a big difference. From 1998 to 2013, the overall coverage of vegetation in Chengdu was good, and the vegetation coverage and the night lights brightness values were signiifcantly negative correlated, the correlation coefifcient is above 0.78.The more intense urban activities, the smaller the vegetation coverage is, that is, in the center of the city, the vegetation coverage has the smallest value, the farther the distance from the city center, the higher the vegetation coverage is. The change of the vegetation around the city where urbanization is developed fast is the largest. As a whole, the degree of vegetation coverage in the Chengdu region remains relatively stable and increase smoothly.关键词
