黄土高原西北部地区的旱度模式

A drought severty model for the northwest Loess Plateau

本文应用帕尔默旱度模式的基本原理,选取平凉等11个站点的资料,建立了适用于黄土高原西北部地区的修正的帕尔默旱度模式。并用此模式分析了本区的干旱特征。结果表明,此模式是分析本区干旱的一个良好工具。

Based on the principles of the drought severity model of developed by W.C.Palmer, a revised model of drought severity for the northwest Loess Plateau has been established in this paper. And the model has been used to analyse the drought character of this region. The results proved that this model is a good tool for drought researching on the region.
