摘要: 采用模式倍程分组法,借助Weibull模型拟合湖北省南漳县漳河源自然保护区铁坚油杉[Keteleeria davidiana (Bertr.) Beissn.]群落的乔木层物种多度分布。结果表明,3个样方乔木层以及3个样方乔木总和的Weibull多度分布模型拟合经2检验,样方1与样方3符合Weibull分布;而样方2与合并样方不完全符合Weibull分布;K-S检验表明,4个取样方式下,乔木层物种多度均符合Weibull分布,其模型应用于铁坚油杉群落乔木多度分布是可行的。

Abstract: Based on model octave grouping method, Weibull distribution model was employed to fit the species abundance of the tree layers in the Keteleeria davidiana(Bertr.) Beissn. community in Zhangheyuan Nature Reserve of Nanzhang county, Hubei province. The results showed that, the Weibull distribution models of the tree layers of 3 consecutive sample plots and 3 samples plots combined were tested with 2, and the fitting models of tree layers in sample plot 1 and sample plot 3 were in accordance with Weibull distribution, while the fitting models of tree layers in sample plot 2 and the sample plots combined were not completely in accordance with Weibull distribution; the K-S test showed that the species abundance of the tree layers was consistent with Weibull distribution through four sampling sources. Comprehensively speaking, Weibull distribution model proves to be applicable to the species abundance distribution of tree layers in K. davidiana communities.

Key words: Keteleeria davidiana (Bertr.) Beissn., community, species abundance, Weibull distribution model, Nanzhang county
