摘要： 本文基于2001-2006年极轨气象卫星遥感影像资料和农业气象观测站的旬土壤墒情资料，同时根据安徽省淮北地区干旱特点，利用距平植被指数与20cm土壤墒情建立了干旱监测模型，分别为y春=0.221x+54.375, y冬=0.4474x+81.447；各指数值反演土壤墒情分布，对模型进行统计检验，结果表明春季和冬季距平植被指数通过显著性检验。

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.
