摘要

对湖南株洲20a生樟树人工林的降雨分配规律进行了2a的观测。结果表明，该森林生态系统年降雨输入为1321.4mm，其中16.869mm以树干茎流形式进入林地，占年降雨量的1.28%，林内穿透水为957.4mm，占72.45%。另外，林冠年截留量为345.749mm，占年降雨量的26.17%。在次降雨中，降雨量越小，截留率越大，雨强越小，林冠截留作用的效益越明显。

Abstract

The precipitation distribution in 20 yearold artificial forestof Circrcamomum camphora in Zhuzhou City

Hu’nan Province was studied. Results show that annual average rainfall of the ecosystem is 1321.4mm

a-mong them the throughfall

stemflowand canopy interception rate make up 72.5%

1.3%and 26.2%of the an-nual precipitation

respectively. In a single rainfall

the less the rain

the higher the interception rate

and the less the rainfall intensity

the more the benefits from the crowntercep tion.
