摘  要:
以江西武夷山国家级自然保护区河岸带阔叶林群落为研究对象,对其物种组成进行调查,并采用物种丰富度指数、多样性指数和均匀度指数分析物种多样性。结果表明,保护区河岸带物种极丰富,三条水系10个样方中共调查到维管束植物93科174属304种,群落建群种和灌木层优势种均以常绿阔叶树种为主,物种组成具有典型的亚热带植被特色,以壳斗科、樟科、山茶科物种最多。保护区不同海拔河岸带物种丰富度指数、多样性指数的变化规律基本一致。

摘  要:
Investigated the species composition of riparian broadleaf forest community in Jiangxi Wuyishan National Nature Reserve, and analysed the species diversity in terms of richness index, diversity index and evenness index. The results show that the riparian zone species is abundant in Reserve, There are 304 vascular plant species, belonging to 174 genera and 93 families, The constructive species of communities and the dominant species in shrub layer are evergreen broad-leaved species, species composition is the typical characteristics of subtropical vegetation,and the largest number of species is Fagaceae, Lauraceae and Theaceae. Variation of reserve riparian species richness index and diversity index is consistent in different altitudes.
