[目的]对兴安落叶松林2种主伐迹地天然的更新特征及生长因子进行分析。[方法]根据大兴安岭兴安落叶松林主伐天然更新固定样地资料建立数据库,通过编程研究大兴安岭北段地区的兴安落叶松皆伐样地和渐伐样地的天然更新特征。[结果]2种主伐方式的天然更新均为良好,且后者的天然更新较前者更好,天然更新幼苗幼树的生长因子之间均存在着显著的线性回归关系。[结论]该研究为今后大兴安岭的森林采伐和更新提供科学的理论指导。
[Objective] The research aimed to analyze the natural regeneration characteristics and growth factors of two main culms in Larix gmelinii forest. [Method] According to the data of natural regeneration fixed - site of Larix gmelinii forest in Daxinganling, a database was established to study the natural regeneration characteristics of clear - cut larch cleared - cut and quadrats in the northern segment of Daxinganling by programming. [Result] The natural regeneration of two kinds of main cutting methods were all good, and the natural update of the latter was better than the former. There was a significant linear regression relationship between the growth factors of the natural regeneration seedling saplings. [Conclusion] This study provided scientific theoretical guidance for future forest cutting and regeneration in Daxing’anling.
