　　为了揭示大兴安岭兴安落叶松群落结构的内部特征问题，以内蒙古大兴安岭牙克石林管局下属6个林区的兴安落叶松群落为研究对象，对兴安落叶松群落结构和种群空间分布格局进行调查与分析。结果表明：兴安落叶松群落结构简单，兴安落叶松单优种，伴生有较少白桦、山杨和樟子松；林分密度差异较大，最大达到了2040株/hm2，最小为340株/hm2。群落林分直径主要分布6~32 cm范围之内，绝大多数林木直径均处于小径级范围内，说明各林场林分均处于旺盛的生长发育时期。兴安落叶松群落种群分布格局呈随机分布、呈均匀分布和集群分布，而聚集分布型居多。

In this paper, the author selected the Larix gmelini community at the Greater Higgnan Mountains as the object of this study to analyze the spatial distribution population patterns and community structure from the stand scale. The major results of this article were hereby described as follows: the tree layer species composition was simple and obvious hierarchy in Greater Higgnan Mountains forest communities, mainly larch, birch, aspen, pine and so on. The density of this community was difference, and the distribution range of 340-2040 plants/hm2. The space distribution of dominant populations of Greater Higgnan Mountains was mainly aggregated distribution, followed by uniform distribution, randomly distributed less likely.
