Abstract: This paper tries to establish the model between the Anomaly Vegetation Index(AVI) and soil moisture(include 10cm and 20cm soil moisture) based on AnHui Huaibei area drought features and polar orbit meteorological satellite data and surface meteorological data. The model between AVI and 20cm moisture is, yspring=0.221x+54.375 ,ywiner=0.4474x+81.447.Then use each index value to inverse the distribution of soil moisture. The result shows that the model between AVI and 20cm soil moisture is significant at 0.05 level in spring and winter.
