| 摘 要： | 着眼北京市密云县古北口镇潮关西沟流域内华北落叶松代表性样地,分别对其不同密度下林木直径和树高结构进行分析,从而找出其林分分布规律。结果表明:华北落叶松人工林的不同林分密度下林分结构相似,基本遵从于正态分布。随着林分密度的增加,林分平均胸径分布范围增加,林分内的树高分布范围也增大,且不同密度林分的树高分布都有一个高峰。

| Abstract: | Taking the representative Larix principis-rupprechti samples in Chaoguanxigou Basin in Gubeikou, Miyun in Beijing, analysis of the tree diameter and height of the different density of samples respectively was conducted to study the forestry distribution rule. The results showed the stand structures of Larix principis -rupprechtii plantation forest under different densities were similar and followed the normal distribution; the stand density decreased with the increase of stand average DBH, tree height decreased with the increase of stand density, and all stand of different density distributions had a peak height. |
