摘要: 观测了川西亚高山白桦次生林一个生长季节内的穿透雨和茎流的特征。结果表明,幂函数方程能较好地拟合林冠截留量、茎流量与总降雨量之间的关系,而线性方程能较好地拟合穿透雨量和总降雨量之间的关系;平均林冠截留量占总降雨量的18.9%,穿透雨量占总降雨量的80.9%,茎流量占总降雨量的0.3%。

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.
