摘　　要：[Objective] This study aims to analyze the natural regeneration characteristics and growth factors of two cut-over lands of Larix gmelini forests in Greater Khingan Mountains. [Method] A database was established based on the information of natural regeneration cut-over sample plots of Larix gmelini forests in Greater Khingan Mountains. Natural regeneration characteristics of clear-cutting sample plot and shelterwood-cutting sample plot of Larix gmelini in the northern regions of Greater Khingan Mountains were investigated by programming analysis. [Result] The natural regeneration of two principal felling systems was both good, and that of shelterwood-cutting sample plot was better. There were significant linear regression relationships among various growth factors of naturally regenerated plants. [Conclusion] This study provided scientific theoretical guidance for subsequent deforestation and regeneration in Greater Khingan Mountains.[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。
