| 摘 要： | 概述了气象干旱和水文干旱的指标种类，并对各指标进行初步评述，同时详细介绍了几种常用干旱指数的计算方法。鉴于以往干旱指标大多比较单一，描述气象干旱和水文干旱的指标彼此独立，因此，今后在针对流域干旱的研究中应加强对于水文干旱和气象干旱的指标耦合，力求建立综合性的干旱指标。

| Abstract: | The index used in describing hydrologic drought and meteorological drought are presented in this paper. At the same time, the characteristics and suitability of the index are compared and analyzed. The results show that the previous index are simple and the index used in describing hydrologic droughtand meteorological drought are separated. So, establishing comprehensive drought index is a new studying area. |
