In this paper, two drought monitoring methods of temperature vegetation dryness index (TVDI) and vegetation supply water index (VSWI) based on temperature／vegetation supply water index (NDVI) were contrasted and analyzed by MODIS data in semihumid and transitional zones in Anhui Province. The grades of TDVI and VSWI about drought monitoring combining accumulated humidity index were established, which were validated by local soil moisture． TVDI and VSWI and accumulated humidity index have been shown a remarkable correlation, and the TVDI drought monitoring method is more suitable than VSWI in researching area.
