摘要: 从地面水平衡的角度出发,用蒸发比作为地面千湿状况的指标。为解决短时段陆面燕发,提出一个新的计算陆面自然蒸发的方法。用新方法计算华北平原和海南岛两种不同类型的干湿状况其结果比通常的方法更符合实际情况。

Abstract: Advantages of using evaporation ratio (E/E0) as surface moisture (aridity) index were demonstrated according to the water balance equation. A new method for estimating the natural surface evaporation (E) in a short period was suggested. Finally, two different type moisture conditions of the North China Plain and the Hainan Island were calculated. The results tallied with the actural situation much more than usual method.
