摘  要:
在自然状态下,广西猫儿山的天然阔叶林在海拔1300~1500m的范围物种多样性指数发生了变化;分别不同海拔梯度对处于原生状态的天然阔叶林取样进行物种多样性和性异性的研究,结果表明,物种在1300~1500m范围的间断也是非常明显的。这个结果与以往对猫儿山植被垂直分布的划分基本一致,在广西猫儿山,海拔1300m是常绿阔叶林和常绿、落叶阔叶混交林的分界线。

摘  要:
In natural condition, the richness, species diversity and evenness index of primary broad - leaved forests in Mao'er Mountain of Guangxi Zhuang Autonomous Region are changed in the range of alt. 1300-1500m. Meanwhile, calculating coefficient of difference and numerical taxonomy in sampling of various alt. shows that the discontinuity of species in this region is obvious . This result approximately identifies with the division of vegetation vertical distribution in the past. In this region, the alt. range is a dividing line, i. e. the lower part is evergreen broad-leaved forest and the upper part is evergreen and deciduous broad-leaved mixed forest.
