摘要
本文主要研究了辽宁东部山区森林枯落物层对降雨拦蓄特征、对降雨的分配情况及自身的持水规律。结果表明：辽东林区枯落物层最大拦蓄雨量为３０～８６ｍｍ；有效拦蓄量为１５～５０ｍｍ；降雨截留率为１９％～２６％；
The characteristics of rainfall interception,the rainfall distribution in forest litter and its waterholding capactity in the eastern mountainous areas of Liaoning were researched.The results showed that the maximum rainfall interception by litter was 3.0-8.6mm;the effective interception 1 5-5 0mm;the rainfall interception rate was 19%-26%;8 0%-14 0% of rainfall in growing seasons was evaporated through forest litter.
