摘要: 本文以能量平衡公式为基础,根据实际蒸发与潜在蒸发的关系依赖于土壤水分含量的事实,导出一种表达干湿状况的指标——土壤水分干旱指数。

关键词: 干旱指数, 气候分类, 地表温度, 蒸发

Abstract: A long history has been experienced to research into the geographical aridity and humidity by use of various indices, This paper briefly reviewed some typical indices in the climatic classifications such as Koppen's, Thorn th-waite's and Budyko's types. Summing up, the indices were gradually developed from empirical, semi-empirical description to physics-based method.it is an opportunity to derive new index as the achievements of earth sciences such as energy balance, water balance and related technique, have been made in the last decades.

Key words: Aridity Index, Climatic Classification Surface Tempaerature, evaporation
