摘　　要：运用对数模型对武夷山风景名胜区不同天然林的物种多度分布进行预测与检验。结果表明:无论是乔木层还是灌木层,物种组成均以少数种为主,多数种个体数较少,说明其物种多度分布的不均匀性和物种间个体数的差异均较明显,其中,乔木层的物种多度级由4到8级,灌木层的物种多度级由2至4级。此外,武夷山风景名胜区天然林中,乔木层和灌木层的群落物种多度分布均遵从对数级数分布,且物种多样性均表现为鼠刺叶石栎群落>杉木群落≥米槠群落>毛竹群落>马尾松群落的趋势,这表明阔叶林的物种多样性比针叶林的丰富。The log series model is applied to calculate and test the species abundance of natural forests in Wuyishan Scenery District. The forests are mainly composed of minority tree species and the tree individuals of majority tree species are few, indicating an unevenness in species abundance and a significant difference in species quantity in both arbor and shrub layers. The abundance grade of the arbor species ranges from 4 to 8, and that of shrub species from 2 to 4. Moreover, species abundance in arbor layer and shrub layer follows a logarithmic series distribution, and the species diversity of both layers displays the trend as Lithocarpus iteaphyllus 〉 Cunninghmia lanceolata ≥ Castanopsis carlesii 〉 Phyllostachys edulis 〉 Pinus massoniana, which shows that the species diversity of the broad-leaved forest is more abundant than that of comiferous forest.
