| 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、格林指数、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及分布模型，研究了南方红豆杉种群的空间分布格局及其动态，结果表明，南方红豆杉种群空间格局为集群分布，从幼苗到大树，春集群程度减小，大树呈随机分布。

| Abstract: | Field data were sampled by the method of contiguous grid quadrate,and t test of v/m ratio,negative binomial parameter,Green's index,Cassie's index,dispersion index,clumping index,mean crowding index and patchiness index were used to analyse the distribution pattern and its dynamics of Taxus chinensis var. mairei population.The result shows that the distribution pattern was clustering.From sapling to grown up tree,the clustering degree was decreasing,while the big trees had a random distribution. |
