Abstract: Drought is a disaster which arises most frequently in the broadest area and has the most severe impact among natural disasters. In recent years,because the loss from natural disasters increased obviously,governments have paid more and more attention to the mitigation works. Scientists have begun to evaluate the impacts of natural disasters, including drought. This paper aims to grasp the actual situation of drought evaluating study and promote its further deepening. The research progress at home and abroad about drought from index,evaluating theory,evaluating methods and evaluating types is summarized. It is found from analysis that now-existing drought evaluating study mainly focuses on agricultural drought and single crop variety drought, lacking the simulation study of drought impact on ecological environment and social economy from a system point of view, and the drought evaluating models can not simulate the systematic impact of drought. It is suggested that future drought evaluating study should use more new techniques and methods and advance to the direction of multidisciplinary and comprehensive study.

Key words: drought, evaluation, progress, study
