本文选用几何级数分布、分割线段、对数级数分布和对数正态分布等模型研究了南岳广济寺森林群落植物物种相对多度的分布格局。结果表明,对数级分布模型适于拟合南岳广济寺森林群落乔木层和灌木层物种相对多度的分布格局;分割线段中的序列一多度模型仅适合于乔木层;对数正态分布模型仅适合于草本层;几何级数分布模型完全适合于拟合任何层次。此外,α指数值亦显示出本群落接近山地季雨林的多样性水平。
In this paper, the distribution pattern of relative abundance of plant species in Guangji Si forest community in Nanyue was studied by using geometric series distribution, segmenting line segments, logarithmic series and log-normal distribution model. The results showed that the log-rank distribution model was fit to the distribution of relative abundance of tree species and shrub species in the Guangji Si community in Nanyue. The sequence-multiple model in the segment of the segmentation was only suitable for the arbor; The distribution model is only suitable for the herb layer; the geometric series distribution model is perfectly suitable for fitting any level. In addition, the α-index value also shows that the community is close to the diversity of mountain monsoon forest.
