文摘内容 The characteristics of throughfall and stemflow over one growing season were studied in a dark coniferous forest in the subalpine of the Western Sichuan. The results indicated that: 1 ) The distribution of precipitation by canopy was more relative to the rainfall, the higher the rainfall was, the more the throughfall and stemflow were, and the less the interception was; 2) The relationships between throughfall (T) and total rainfall (P) could be described significantly by a linear function ( T = 0.744 P-0.937, R^2 = 0.954, p < 0.001), while the reationship between crown interception (I) and total rainfall by a power function (I= 0.759P^0.666, R^2 =0.763, p<0.001); 3) The average canopy interception accounted for 35.8% of total rainfall and the average throughfall for 64.2% , and the average stemflow for 0.01% ; 4) High water-hold capacity of moss on the surface of tree trunk and low rainfall intensity were the main reasons that the stemflow of the coniferous forest in the subalpine of Western Sichuan was less than other forests。
