| 摘 要： | 采用相邻格子样方法取样数据，应用方差／均值比的ｔ检验法、负二项参数、扩散型指数、Ｃａｓｓｉｅ指标、丛生指标、平均拥挤指数和聚块性指数等方法，分析了四川大头茶种群在不同群落中的空间分布格局．结果表明：在不同群落中，其空间格局均为集群分布，但集群程度有所差异．此外，还分大小级对四川大头茶种群的分布格局进行分析，从幼苗到乔木，其集群程度从大到小。

| Abstract: | The contiguous grid quadrats have been applied to sampling for field data. 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 Gordonia acuminata population in different plant community. The results show that the distribution pattern is of the clump in different plant community, but the intensity is different. In addition, the analysis of distribution Pattern has also been done according to size classes. From saplings to grown-up trees, the degrees of intensity is decreasing from high to low. |
