摘要
林冠截留降水是森林植被对降雨到达地面的阻截,也是对大气降雨的再分配,是水文循环过程中的重要环节。本文分析当前森林冠层水文过程研究,即林冠截留、透流和茎流及影响因素(降水量、降水强度、林冠结构特征、林分密度、林冠干燥度);林冠截留模型的国内外研究现状(经验、半经验、半理论和理论模型)的分析。
Rainfall interception by vegetation is the first loss and the first redistribution of rainfall.It reduces the rainfall effectively and so is one of the important processes of water cycling.This paper analyzed the current research situations on the hydrological process of forest canopy from the aspects of forest canopy interception,throughfall and stemfall,and its influence factors（rainfall,rainfall intensity,canopy configuration,stand density and dry degree）.Canopy interception models（empirical,half empirical,half theoretical and theoretical models）were also reviewed.
