Abstract

In this paper, use the data of FY3A equipped with medium-resolution spectral imager (MERSI), base on drought monitoring model (PDI、VSWI and MSAVI) to drought monitoring and analysis in the eastern part of Gansu Province,2012, combined with meteorological part of precipitation, temperature, and meteorological drought data were compared the analysis showed that the drought monitoring model based on the inversion of FY3A/MERSI satellite data can objectively reflect the spatial distribution of drought in the study area and the dynamic development process, significantly different model of monitoring the appropriate drought monitoring and differences; The drought level was verified by the soil moisture obtained in field work. The relationship of drought severity and soil moisture with soli depth of 0-10cm, 0-20cm and 0-40cm was shown: There is a good relationship between the three drought indexes and the corresponding soil moisture.
