摘要： 为了探讨以蒸散发为基础的干旱监测模型在山西省干旱业务监测中的应用效果，便于为抗灾减灾提供数据支持，利用风云三号、风云二号气象卫星数据，结合自动站气象数据，基于SEBS模型对山西省进行干旱监测研究。结果表明：监测结果总的分布与实测结果基本吻合，但在干旱的面积和程度上均略高于实测结果，同时CWSI能实时体现降雨量对土壤墒情的影响，对山西省干旱业务监测具有一定的现实意义。

Abstract: In order to study the application effect of drought monitoring model based on evapotranspiration in Shanxi Province, and provide a data base for the disaster prevention and mitigation. The author monitored drought based on SEBS model in Shanxi Province with remote sensing date from FY3A/3B and FY2E satellite, and meteorological date from automatic meteorological station. The results showed that: this method improved the monitoring accuracy, which was slightly higher than the measured results on the area and extent of the drought, the CWSI reflected the influence of precipitation to soil moisture, and it had a certain practical significance to drought monitoring in Shanxi Province.
