摘要

以河北省木兰林业管理局的北沟林场作为试验基地

通过实地调查

对不同密度的落叶松林地进行了详细的测量

分析了不同落叶松人工林密度对落叶松林个体生长状况等因子的影响。结果表明

在一定林分密度范围内

随着林分密度的增加

林分胸径、冠幅呈减小趋势

二者呈幂指数函数关系;单株材积呈递减趋势

蓄积量呈递增趋势

单株材积和蓄积量与密度也符合函数关系规律。

Abstract

This study was conducted in the Beigou forest farm of Mulan Forestry Authority in Hebei Province. In a field investigation

detailed measurements were made for the different densities of Larix principis. Results show that as the stand density increases

both stand diameter at chest height and crown width decrease

which have an exponential relation to the density. Single-tree volume decreases progressively

while stock volume increases progressively. The single timber volume and store are also related to the density.
