摘要
本文用雨强和所谓“干度”这两个时间与空间的函数,建立了描写林冠对降雨截留过程的微分方程组,以及计算截留量的公式。在其中,所有参量都是可测量的。
In terms of rainfall density and so-called 'dry percent' both ofwhich are functions of time and space, a group of differential equations describing intercepted process of rainfall in forest canopy is established,and a formula calculating amount of rainfall interception is given.Allthe parameters in them are measurable quantities.
