%X Based on soil moisture and its MODIS data in different depth from 20 soil monitoring stations in north Shaanxi,three kinds of drought remote sensing indices,including the modify energy index(MEI),perpendicular drought index(PDI)and the surface water capacity index(SWCI),was calculated,and the spatial distribution of droughts with different grades was formed.The results showed that 20cm was the best depth for monitoring soil moisture by three drought remote sensing models,followed by 10cmA dynamic inverse of relative soil moisture during the growing season from April to September in 2008 showed that all of the three indices could monitor soil moisture and drought proper and timely in region.So they are suitable for this study area.
