| Abstract: | The characteristics of throughfall and stemflow over one growing season were studied in a 30 year old Betula platyphylla secondary forest at the subalpine of Western Sichuan.The results indicated that The relationships between canopy interception,stemflow and total rainfall could be described significantly by a power function,while the relationship between throughfall and total rainfall is linear. The average canopy interception accounted for 18.9% of total rainfall,and the average throughfall accounted for 80.9%,while the average stemflow accounted for 0 3% of total rainfall in the forest in the measuring period. |
