摘　　要：　2004年,在三峡库区莲峡河小流域马尾松林地进行了大气降水、林内透雨、树干茎流的测定,进行了林下枯落物和土壤对降雨影响的研究.结果表明:观测期,马尾松林内透雨占大气降水总量的76.70%,林冠层截留量占降雨总量的23.03%,树干茎流占降雨总量的0.27%;林下枯落物的最大持水量为3.40mm,林地0～40cm层土壤饱和蓄水量为183.60mm;林内透雨、树干茎流、林冠截流与大气降水量以及降雨强度具有显著的二元线性相关关系.<Abstrcat>The precipitation, the throughfall, the stemflow, the litter form and the soil interception are measured in Lianxiahe Watershed of Three Gorges Reservoir Area in 2004, the results show that the throughfall is 76.70%, the canopy interception (23.03%), and the stemflow 0.27% of total of precipitation. The maximum water holding capability of litter form is 3.40 mm and the soil layer from 0～40 cm can reserve 183.60 mm water. The relationships of the precipitation quantity and intensity to the throughfall, the stemflow and the canopy interception are binary linear regressions.
