基于MODIS的河南省遥感干旱监测研究
Remote Sensing Monitoring for Drought in Henan Province Based on MODIS
摘要
Abstract
Large scale drought monitoring based on remote sensing plays an important role and however,only a few studies of the spatial adaptability about a variety of remote sensing drought indexes in different regions were conducted.Normalized difference vegetation index（NDVI）,anomaly vegetation index（AVI）,vegetation condition index（VCI）,and temperature condition index（TCI） were separately calculated based on MODIS images of He′nan Province and its drought situation in the latest decade was analyzed in combination with traditional meteorological drought index.Results showed that droughts occurred at different extents in six years between 2000 and 2009 and the northern and western parts of He′nan Province were more prone to suffer from severe droughts.Result from remote sensing monitoring for drought was consistent with the meteorological drought index.After analyzing the correlation between remote sensing drought index and meteorological drought index in different periods and regions of He′nan Province,four indices were found to have spatiotemporal adaptability.The research provides a technological support for drought monitoring.关键词
