【中文摘要】 采用方差/均值比率法測(cè)定了鵝膏屬種群的分布格局類型。結(jié)果表明,47個(gè)鵝膏屬種群,有1/4屬于集群分布類型,有3/4屬于隨機(jī)分布類型。隨機(jī)分布的種群其聚集強(qiáng)度指標(biāo)擴(kuò)散型指數(shù)、叢生指數(shù)、聚塊性指標(biāo)和平均擁擠度多對(duì)1.0沒(méi)有顯著的偏離,負(fù)二項(xiàng)參數(shù)則較大;而聚集分布的種群其聚集強(qiáng)度指標(biāo)則符合聚集特征。

【英文摘要】 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.
