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.
