基于AMSR-E数据的微波植被指数与MODIS植被指数关系研究
Relationship between microwave vegetation index based on AMSR-E data and vegetation index based on MODIS data
摘要
Abstract
Microwave Vegetation Indices（MVIs） in the pastoral area of the south of Qinghai Province were calculated by using AMSR-E brightness temperature data from 2007 to 2010 and its features of monthly MVI changes were discussed,and then the relationship between microwave vegetation index based on AMSR-E data and vegetation index based on MODIS data for same time series was determined in this study.This study showed that the MVI value reduced as the vegetation plant grew and the MVIs was strongly negative correlations with NDVI and EVI,in which the correlation between MVIs and NDVI was the best with the correlation coefficient of 0.58.The optimal model between MVIs and MODIS vegetation indices wasNDVI=-0.85×MVI＋0.84,and the comparison result showed that the difference between MODIS NDVI and simulated NDVI from the optimal model was little.This study suggested that the optimal model reflected the relationship of the two vegetation indices.关键词
