[目的]研究谷城不同天然红椿群落的物种多样性。[方法]设立样方对2个群落的乔灌草进行调查，针对不同群落、群落间乔灌草分层α多样性进行分析。[结果]结果表明，地形、土壤理化性质、植被类型对不同群落整体α多样性分布特征影响不大。干扰造成群落间共有种按草、灌、乔递减，群落物种均匀度依次下降，群落间灌木层和乔木层α多样性差异极为显著，进而对整个群落的结构、组织、稳定和发展造成影响。[结论]研究结果为红椿的保护和可持续利用提供了理论依据。

Objective] The aim was to study the species diversity of different Toona ciliata communities in Gucheng region. [Method] The sample plots in two different communities were established to survey the arbor-shrub-herb layers, andαdiversities between communities and between different plant layers were analyzed . [Result]The results indicated that factors, namely, soil physicochemical properties, topography, vegetation form had a minor impact on α diversity distribution characteristics of different communities, while human disturbance contributes to the decline of common-shared species in two communities in the order of herb, shrub and arbor layers and that of species evenness as well, extremely significant difference in α diversity between shrubs and arbors of two communities, and furthermore, the structure, organization, stability and development of the entire communities. [Conclusion] The results provided theoretical basis for conservation and sustainable use of Toona ciliate.
