摘要 干旱灾害是世界各国,尤其是我国最为严重的自然灾害之一。不同领域、不同应用中所定义的干旱指标各不相同。气象干旱是其他各类干旱的基础,而帕默尔(Palmer)干旱指标是气象干旱的主流指标,有着广泛的影响,该指标能反映干旱的成因、程度及开始、结束和持续时间,具有物理意义明确、涉及资料容易获得和参数计算简便等特点。根据国内外大量文献,对帕默尔干旱指标的研究进展进行了回顾,对其应用进行了总结,同时对未来帕默尔旱度模式的进一步修正进行了展望。 The drought is one of the most severe meteorological disasters in the world, and especially in China. The research on drought involves wide variety of disciplines. Because of the diverse geographical and temporal distribution of drought, and different scales of drought impaction, it is very difficult to develop a definition to describe drought and also an index to measure it. All kinds of drought are based on the meteorological drought. Parmer drought severity index (PDSI) is an important climatological tool for evaluating the scope, severity, and frequency of prolonged periods of abnormally dry or wet weather. It can be used to delineate disaster areas and indicate the availability of irrigation water supplies, reservoir levels, amount of stock water, and potential intensity of forest fires. In this paper, PDSI and it's application were summarized, and development for further modification of the PDSI Model was forecasted.
