| 摘 要： | 本文应用坡相四个因子在两个水平下的正交试验设计方法，系统分析了１７年生杉木人工林和２２年生湿地松人工林木材密度的变化规律，结果表明：影响杉木人工林和湿地松人工林木材密度的最重要坡相因子是坡形，其次是坡位，坡向和小于４５°的坡度影响不显著。

| Abstract: | In this essay an orthoganal design with four slope factors under two levels is carried out to systematically analyse the law variation of on wood density of 17 year Chinese and 22 year slash pine from plantations. The results show that slope form is the most important factor influencing wood density of Chinese fir and slash pine from plantations, and position on the slope is the secondary, while slope aspect and slope with less than 45 degree influence the wood density insignificantly. |
