| 摘 要： | 应用正交试验设计方法，系统分析了不同林龄，立地条件和林分密度下杉木人工林木材化学成分含量的变异规律。结果表明：影响人工杉木林木材化学成分含量的主导因子是林龄，其次是立地条件，林分密度影响最小。综合人工杉木林不同林龄，立地条件和林分上木材化学成分含量考虑，其纸浆材主伐年龄以１７－２３年左右较好。

| Abstract: | By using orthogonal design, this paper systematically analysed the law of variation in chemical compositions of Chinese fir was from plantations, which with different ages and densities, and grown in different sites. The results showed that the degree to which each factor affects the chemical compositions of Chinese fir wood was determinated as: the frist is age, the second is site, and the third is density; Based on variation in chemical composition in the different ages, densities and sites, the better harvesting age of Chinese fir for pulpwood is about between 17 and 23 years. |
