| 摘 要： | 林冠结构对于森林生态系统降水截留有着重要的影响。本文应用树体管道模型理论,构建了长江上游针叶林优势树种峨眉冷杉的树体管道模型,建立了管道参数与林冠截留量的关系。结果表明:峨眉冷杉树冠的叶量、侧枝与树干的截面积都随高度交替增长,最大值出现在树冠中下部;同一层次内的叶量与枝量存在极显著的比例关系;建立的树体管道参数反映了树干及侧枝承载叶量的能力,与林冠截留量呈线性相关关系。

| Abstract: | Canopy architecture has important affect on its ecosystem precipitation interception.The paper hereby employed pipe model theory to construct the pipe model of Abies fabric,dominant tree species in dark coniferous forest at the upper reach of Yangtze River and establish the relationship between pipe parameter and canopy interception storage.results showed that the leaf weight、sectional area of branches and trunk were alternating growth with the height and the maximum value appeared in the lower part of the crown;leaf weight and quantity of branches in the same level existed significant proportion relationship;the pipe parameter,representing the capability of stem and branch to brace foliages,was linearly correlated to canopy interception storage. |
