摘要
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,通过对群落物种多样性的量化分析,探讨大兴安岭兴安落叶松群落物种多样性分布规律。结果表明:兴安落叶松群落种群物种多样性总数分布范围为0~28种,垂直结构上变化规律明显,草本层物种数最多,其次是灌木层,最小的是乔木层。群落丰富度最大的为阿里河西陵梯林场,主要是灌木层,草本层物种较多。最小的为克一河库亚林场的兴安落叶松群落,该群落草本层物种较小。
In this paper, it selects the Larix gmelini Community at the Greater Higgnan Mountains as the object of this study to analyze the species diversity distribution law of the Greater Higgnan Mountains forest community from the stand scale. The major result of this article were hereby described as follows: Among the 18 forest plant communities in the Greater Higgnan Mountains the total number of the species distribution range of 0-28 species, and the variation on the vertical structure of community showed the herbaceous layer species richness index above the shrub layer and tree layer. The highest species richness appeared in Larix gmelinii communities of Alihexilingti forest with more species of shrub and herb layers. The lowest species richness appeared in Larix gmelinii communities of Keyihekuya forest with less herb layer species.
