为研究谷城县天然红椿群落的物种多样性和红椿种群的分布格局，通过野外调查，采用样方法，运用7种多样性指数研究两个样地的乔灌草多样性，并对各多样性数据进行相关性分析；采用相邻格子样方法，运用7种不同分布格局指数，对不同红椿种群的空间格局进行系统研究。结果表明：不同样地灌木和乔木层香农指数差异显著；乔灌草层各样性指数间相关性较高；不同样地种群分别为集群分布和泊松分布。人为干扰造成群落不同样地草灌乔多样性下降，种群分布格局变化；天然红椿种群呈泊松分布，人为干扰下呈聚集分布。

Aiming at the species diversity of Toona ciliata community and the distribution pattern of the populations in Gucheng region and establishing the sample plots in two different communities to survey the arbor-shrub-herb layers,we analyzed the species diversities between two plots in different plant layers by using quadrate sampling method and studied the correlation between various diversities indexes and discussed the spatial distribution of the populations.The result indi-cated that there were significantly different among Shannon indexes of shrub-and-arbor layers in different plots;The di-versity indexes of arbor-shrub-herb layers were highly correlative;The populations were different distribution patterns. Human disturbance contributed to the decline of species diversity in two sampling plots and the different distribution pat-terns,one was Poisson distribution in natural condition and the other was clumped distribution under human disturbances.
