以山西省汾河流域为例，采用水量和能量平衡原理的VIC模型模拟了区域内径流和土壤含水量的变化过程，并构建了土壤干旱指数进行实例研究。结果表明：建立的VIC模型能够较好地模拟研究区站点的径流和土壤含水量的变化过程，基于土壤含水量模拟的土壤干旱指数与实际干旱的发生具有较好的相关性，土壤干旱指数物理意义清晰，能较好地刻画区域干旱在时空上的发生、发展及结束过程，对区域干旱监测具有一定的应用价值。

The paper used variable infiltration capacity model to simulate the variable process of runoff and soil moisture in the region based on the principle of water and energy balance taking Fenhe river ba -sin in Shanxi province for example .The soil drought index ( SDI ) was constructed and applied in the study area .The results showed that the VIC model can better simulate the variable process of runoff and soil moisture .The simulated SDI has better relativity with the actual drought .The physical significance of SDI is clear and can better depict the process of occurrence ,development and ending in time and space of region drought .The method has certain application value for regional drought monitor .
