摘要: 用β多样性分析环境的异质性表明,八大公山不同地点(杉木界、天平山、斗篷山)的β多样性指数差异很大。随着海拔升高,每梯度每样地的平均物种数逐渐减少,每样地的平均新增物种数也逐渐减少。通过分析各样地的物种分布格局表明,所有植物分布为随机分布。用系统聚类法对种-多度关系进行分类,66块样地分为14类。比较符合实际情况。极其相似的样地对有10个,较相似的有20个。

Abstract: Using Beta-biodiversity index to analyse the environmental heterogenousity in Badagong Moun-tain in Hunan province,the study showed that there were very significant differences between the values in different sites(Shamujie,Tianping Mountain,Doupeng Mountain).The mean number in each sample per gradient of species and new increasing species gradually declined with the increase of the elevation.The species in each sample distributed randomly.All 66 samples could be divided into 14 types by using systematic duster method to analyse the relationship between the species and the abundance.This was accorded with the actural situation.10 sample pairs were extremely alike.And 20 sample pairs were alike.
