摘    要: 暖温带灌丛的生物多样性的研究表明:1.灌丛群落的均一度指数同优势度指数的相关性较丰富度指数同变化度指数的相关性为高;在众多的多样性指数中,D4(Shannon信息度指数)和D6(Gini指数)因最大限度地包含了其它各类多样性指数的信息而被采用。2.灌丛群落的物种多样性指数值随着演替的进行,没有表现出降低的趋势。3.生物多样性较高的荆条灌丛和辽东栎萌丛的物种多度分布是对数分布,而生物多样性较低的鬼见愁灌丛和毛榛灌丛的物种多度分布是几何分布,处于中间的三桠绣线菊灌丛的物种多度分布是Broken-Stick分布;没有正态对数分布类型。

关 键 词:暖温带灌丛  物种多样性  物种多度分布

Abstract:The results of the study show: (1) Eveness indices corellated more closely with dominance than did variety indices with richness indices. Among these indices,D4 (Shannon entropy) and D6(Gini index) highly contained the information of all the indices. (2) The species diversity indices of the scrubs did not decreased from initial stage to middle stage and to climax stage of succession. (3) Species abundance distributions were log series in the scrubs of Vitex chinensis and Quercus liaotungensis where biodiversity was relatively high. Species abundance distributions were geometry series in the scrubs of Caragana jubata and Corylus mandshurica where biodiversity was reletively low. Species abundance distributions were Broken-Stick model in shrub communities of Spirae atrilobata where biodiversity was intermediate. There was no log -normal distribution.
Keywords:Species diversity  Species abundance distribution  Scrub  Succession  Warm temperate Zone  China
