摘要
本文阐述了帕默尔干旱指标的原理、优点及其计算方法。文中用济南和郑州两站的资料对帕默尔干旱指标进行了修正,建立了适合我国东部地区的干旱指标,并计算了我国东部地区150个站(1951.1～1980.12)的干旱指数值,分析了我国东部地区的干旱特征。根据其干旱普遍存在、持续期长和强度大的特点,提出了相应的干旱对策。
This paper expounded the principle and advantage of the palmer's drought severity index and its procedure of computation of the index. Based on the observation from Jinan and Zhengzhou we modified the palmer's drought severity index to fit the observational data. With this modified index we analyscd the characteristic of common existence and long duration and intense severity of drought in the eastern part of China,advanced corresponding drought measures.
