| 摘 要： | 本文观测了桃李两种经济林的穿透雨和茎流特征。结果表明,两种经济林的穿透雨量、林冠截留量、茎流量与降雨量均存在极显著的正相关关系。用幂函数方程能较好的拟合林冠截留量与降雨量之间的关系,而用线性方程能较好的拟合穿透雨量、茎流量和降雨量之间的关系;桃李两种经济林穿透雨量分别占降雨量的93.29%、85.34%,林冠截留量分别占降雨量的5.60%和12.04%,茎流量分别占降雨量的1.11%和2.62%。

| Abstract: | In this papar studies are made of the characterisatics of throughfall and stemflow in peach forest and plum forest.The results have indicated that there exists evidently a positive correlation between the throughfall and total rainfall in two kinds of economic forest and the canopy interception and stemflow are closely related with rainfall too.The relationship between canopy intercaption and total rainfall can be better described by a power function,while the relationship among throughfall,stemflow and total rainfall is linear.The canopy interceptions in these two kinds of economic forest account for 5.6% and 12.04% of total rainfall respectively.And their throughfalls account for 93.29% and 85.34% respectively,while their stemflows account for 1.11% and 2.62% of total rainfall respectively. |
