在对东北蛟河林场３２ｈ ｍ ２ 阔叶红松林每木调查的基础上，研究了阔叶红松林主要树木种群的径级结构，分析了阔叶红松林主要树种的更新模式及其机理．结果表明，阔叶红松林中不同树种的最大径级及其在不同径级中的株数分布不同，阔叶树种的最大径级大都低于针叶树种．根据不同树种按径级的株数分布特征，可将阔叶红松林中的主要树种分为四类．根据不同树种各径级的累计株数百分率曲线所拟合的方程，亦可将阔叶红松林中的主要树种划分为四种类型．以林木种群的径级结构为基础，文章阐述了树木径级结构的平衡性，分析了阔叶红松林主要树种的更新模式及其与自然干扰状况和不同时空尺度的关系，探讨了样地大小对阔叶红松林种群结构研究结果的影响．
Based on the investigation of 3 2 h m 2 broad-leaved Korean pine forests in Jiaohe Forest Farm in northeastern China, the diameter-class structure of the major tree species in the broad-leaved Korean pine forest was studied, and the regeneration patterns and its mechanism . The results showed that the maximum diameter of different tree species in broad-leaved korean pine and its distribution in different diameter classes were different, and the maximum diameter class of broad-leaved tree species was mostly lower than that of coniferous species. According to the distribution characteristics of different tree species according to the diameter class, the main species of broad-leaved Korean pine can be divided into four categories. Based on the equations fitted by the cumulative percentage curves for different tree species in different orders, the main tree species in the broad-leaved Korean pine forest can also be divided into four types. Based on the diameter-class structure of tree species, the article described the balance of the tree-level structure, the updated patterns of major tree species in the broad-leaved Korean pine forest and their relationship with natural disturbance and different time-space scales. Effect of Study on Population Structure of Broad - leaved Korean Pine Forest.
