For the complexity of land surface and the climatic variation, the result of drought monitoring maybe couldn’t give us satisfaction only by using the single remote sensing index. A new solution of the problem was put forward. An integrated linear weighted drought monitoring index (IMDI) was suggested, which is incorporated with remote sensing index （TVDI）constructed by EOS/MODIS data and meteorological factor, named percent of precipitation departure (PPAI). Two periods had been selected to monitor drought in Wuling Mountain area including mid- and the late April in 2011. By comparing with soil moisture in 10cm depth from the observatories around the same area in 2010 and 2011, together with contrasting the correlations with SPI, IMDI and TVDI were confirmed to be able to monitor drought distribution in such a large and complicated area and IMDI is superior to TVDI. However, drought monitored by SPI may be more serious than that of actual situation.
