摘　　要：采有相邻格子样方法取样 ,应用方差 /均值比的t检验、负二项参数、Cassie指标、扩散型指数、丛生指标、平均拥挤度和聚块性指数等方法 ,研究了川鄂连蕊茶种群的空间分布格局。结果表明 ,在不同群落类型中 ,川鄂连蕊茶空间格局均为集群分布 ,但集群程度有差异。同时 ,还对不同发育阶段川鄂连蕊茶种群的分布格局进行了分析 ,从幼苗到成体 ,其集群强度由大到小。The contiguous grid quadrats have been applied to sampling for field data.The methods such as V/m ratio t-test,negative binomial parameter,index of dispersion,Cassie index,index of clumping and index of patchiness have been used to analyse the distribution,pattern of Camellia rosthorniana population in different plant communities.The results showed that the distribution pattern was of the clump in different plant communities,but the intensity was different.In addition,the analysis of distribution pattern was done according to development stages.From saplings to adults,the degrees of clump decreased from high to low.
