| 摘 要： | 以盖度作为物种多度指标，用描述物种多度分布的模型：断棍分布、几体级数分布、对数级数分布和截尾对数正态分布研究了卧龙巴郎山岷江冷棚林线交错带附近草本群落的种－－我镀分布关系。结果表明，截尾对数正态分布和对数级数分布能较好地拟合交错带附近群落的种－多度分布，截尾对数正态分布模型更适合交错带群落，对数级数分布 较好地适合亚高山草甸群落。对数级数分布的参数α和对数正态分布的参数λ是反映群落结构特征内在性质

| Abstract: | By using species abundance distribution models Broken Stick,Geometric Serices,Log Series and Truncated Log Normal,percent cover of every species was used as indicator of abundance to study species abundance relations of herb communities along transects across subalpine timberline ecotone of Abies faxoniana forest in Balang Mountain of Wolong Natural Reserve,Sichuan Province,southwestern China.The results showed that Truncated Log Normal and Log Series distribution models can well fit to the species a... |
