| 摘 要： | 对丹江口库区马尾松林、柏木林和栎类阔叶林3种主要森林类型及单木树干茎流特征进行了研究,结果表明:3种森林类型树干茎流率为0.58%～7.69%,树干茎流量与降水量成线性相关,回归方程达到极显著水平;不同树种间的树干茎流量差异显著,影响树干茎流量的主要因子是冠型结构、胸径、树皮特征和分枝角度。

| Abstract: | The characteristics of precipitation and forest stem flow were studied in Danjiang Reservoir area. The results showed that the rate of stem flow was 0. 58%～7. 69% in three main forest types. There was a prominent linear relationship between the stem flow and the precipitation quantity. There were significant differences in stem flow among different species, and the main factors that affected the stem flow were crown structure, DBH, bark characteristics and branch angles. |

| Keywords: | precipitation forest types stem flow tree characteristic |
