摘要
本文应用几何级数分布、分割线段、对数级数分布和对数正态分布等4种模型研究了南岳上封寺森林群落植物物种相对多度的分布格局。结果表明,几何级数分布模型适宜拟合乔木层和草本层,而不适宜于灌木层;分割线段模型适宜于乔木层,其中,多度一频度模型还适于草本层;对数级数分布模型完全适宜于拟合任何层次;对数正态分布模型仅适宜于拟合乔木层。此外,α-指数值介于季雨林-稀树草原之间。
This paper uses four models of the distributional pattern of species relative abundance, which are the models of Geometric series distribution,Broken-stick, Log series distribution and Log normal distr ibution,and which study the distributional pattern of species relative abundance of forest community in Shanfeng Temple of Nanyue of Hunan pro vince. The results show that the Geometric series distributional model is suitable for imitating the arbor layer and herb layer, but isn't suitab le for imitating the shrub layer,that Broken - stick model is only suitable for imitating the arbor layer, and ' Abundance -Frequency 'model of Broken -stick is suitable for imitating the herb layer, that Log series distribu tional model completely is suitable for imitating any layer,and that Log normal distributional model is only suitable for imitating the arbor of forest community in Shangfeng Temple of Nanyue. Besides, the value of a -index of this community is situated the diversity between Seasonal rain forest and Savanna.
