摘　　要：对干旱发生发展的实时监测、预警及后期影响评估,可最大程度地减轻干旱对农业生产的影响。综述了中国农业干旱的监测、预警及灾损评估的研究与业务应用状况。对比了不同土壤水分监测方法,介绍了具有自主产权的自动土壤水分观测仪Gstar-1及基于MODIS数据构造的土壤水分遥感监测新指数——农田浅层土壤水分指数(CSMI),分析了中国的灾损评估状况。根据目前研究中存在的问题,提出了将来的研究方向。This paper reviews the researches on agricultural drought monitoring, forecasting and loss assessment as well as the applications in China. While discussing and comparing different soil moisture monitoring methods, the paper focuses on Gstar-1 which is an automatic soil moisture detector with our own independent property right, and CSMI a new remote sensing monitoring index for soil moisture based on MODIS data, and gives a comprehensive introduction to the loss assessment in China. Through the real-time monitoring, forecasting and assessment of drought occurrence and development, this paper discusses how to reduce the influence of drought on agricultural production to the largest extent. Finally, some future research directions are proposed.
