| 摘 要： | 采用方差／均值比率法测定了鹅膏属种群的分布格局类型。结果表明，47个鹅膏属种群，有1／4属于集群分布类型，有3／4属于随机分布类型。随机分布的种群其聚集强度指标扩散型指数、丛生指数、聚块性指标和平均拥挤度多对1．0没有显著的偏离，负二项参数则较大；而聚集分布的种群其聚集强度指标则符合聚集特征。

| Abstract: | The distribution patterns of Amanita population were analyzed by means of variance/mean ratio method.The results were as follows: of 47 Amanita species,11 species belonged to clumped distribution and 36 species belonged to random distribution. To randomly distributed population, there were not any signicanct deviations from 1.0 on index of dispersion, index of clumping, index of patching and index of mean crowding, but the value of nenative binomial parameter is high. To clumped populations, those index above are identical with the characters of clumped populations. |
