The distribution pattern of ten Tsuga tchekiangensis populations in the Mang Mountain were analyzed by the variance/mean ratio method,and their aggregated intensities were were measured by using the following indices:negative binomial parameter,dispersal index,clumping index,crowing mean index and patchiness index.

采用方差/均值比率法对10个南方铁杉种群的分布格局类型进行了分析，同时，采用负二项式参数、扩散性指数、丛生指数、平均拥挤度指数和聚块性指数计测这些种群的空间聚集强度。

And such methods V/m ratio t-test, negative binomial parameter, index of dispersion, Cassie index, index of clumping, index of mean crowing and index of patchiness are employed to analyse various dominant populations of Heptacodium miconioides community in the Tiantai Mountain in Zhejiang province and distributive patterns of Heptacodium miconioides community in different quadrats, and this paper also examines the intensity of Heptacodium miconioides population in different quadrats by means of stand classes.

摘 要 以浙江省天台山七子花群落为研究对象，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，分析了七子花群落各优势种群以及七子花种群在各样地中的分布格局，并分立木级对七子花种群在不同样地内的集群强度进行了测定。

We studied its distribution pattem by using the following measures f the test for fitting to the poisson , negative binomial and neyman a distribution . at the same time , we use negative binomial parametef , dispersal index , patchiness index , cassie s index and clumping index , estimated the aggregation intensity . the results showed that the distribution pattern is typically aggregated , and the intensity of aggregation vari

经统计分析，青岛百合复合种群、各局部种群内个体的分布格局离散分布拟合的结果符合负二项分布；各聚集强度参数中，丛生指标）和 cassie 指标均大于o ，负h项参数限）均较小，扩散系数k卜扩散型指数）和聚块性指标均大于1 ，以上这些表明各个局部种群的分布格局都为聚集分布。
