摘要: 在内蒙古大兴安岭绰尔古营河林场设置了3块具有代表性的样地,基于野外调查数据,分析了兴安落叶松群落树种组成结构、直径树高分布、种群分布格局以及物种多样性。结果表明:1)绰尔样地Ⅰ、样地Ⅲ为兴安落叶松纯林,密度分别为740株/hm2和380株/hm2,样地Ⅱ是以兴安落叶松为主并有白桦、黑桦、山杨的混交林样地,密度为1 080株/hm2;2)兴安落叶松纯林(样地Ⅰ和样地Ⅲ)的空间分布格局为均匀分布,以兴安落叶松为主的混交林地(样地Ⅱ)的种群为聚集分布;3)丰富度指数、多样性指数垂直规律一致:草本层>灌木层>乔木层。

Abstract: Based on the field investigation of 3 sample plots of Larix gmelinii in Chaoer of Inner Mongolia,this paper analyzed the tree species composition structure,diameter and height structure,distribution patterns and species diversity.The results showed that:(1) SampleⅠand sample Ⅲ were all pure forest of Larix gmelinii. The density is 740 No./hm2 and 380 No./hm2.sampleⅡwas mixed forest of Larix gmelinii,Betula platyphylla,Betula dahurica Pall and Davidiana dode.The density is 1080 No./hm2.(2)The pure forest of Larix gmelinii (sampleⅠand sample Ⅲ) was in regular distribution,the mixed forest(sampleⅡ) was aggregated distribution.(3)The species richness and species diversity index in the community vertical structure are:herb layer >shrub layer >arbor layer.

Key words: community structure, distribution patterns, species diversity, Larix gmelinii, Inner Mongolia Daxing’anling Mountains
