以江西武夷山典型中山阔叶林为研究对象,在30 km2固定样地设置16个样方,其中13个常绿阔叶林群落、3个落叶阔叶林群落.群落乔灌层物种丰富,占物种生活型的83％.共调查到植物58科112属186种,以壳斗科、山矾科、蔷薇科、山茶科、樟科物种数最多,建群种主要为多脉青冈、闽皖八角、白檀、枫香树等,灌木层以山矾科、山茶科、禾本科为主.物种科属分布区类型以热带性质为主,具有典型的中亚热带地区特点.常绿阔叶林群落和落叶阔叶林群落均具有较高的多样性,单因素方差结果显示这2种林型在多样性指数上不存在差异显著性,乔、草优势种重要值亦不存在差异显著性,只有灌木层重要值存在差异显著性.%Set 16 plots in 30km2 fixed sample area of typical mid-mountain broad-leaved forest in Jiangxi Wuyishan,including 13 evergreen broad-leaved forest communities and 3 deciduous broad-leaved forest communities.The communities have rich species in tree layer and shrub layer,which accounting for 83％ of species' life forms.A total of 186 vascular plant species,belonging to 112 genera and 58 families,were recorded,and the largest number of species is Fagaceae,Symplocaceae,Rosaceae,Theaceae and Lauraceae.The mainly constructive species are Cyclobalanopsis multiervis,Illicium minwanense,Symplocos paniculata and Liquidambar formosana etc.,and the shrub layer dominant families are Symplocaceae,Theaceae and Gramineae.Areal distribution type of species suggests that the forest is typical characteristics in subtropical regions and highly related to tropic components.Evergreen broad-leaved forest community and deciduous broad-leaved forest communities both have high species diversity; one-way ANOVA results showed that there is no significant difference on the diversity index of the two forest types,so do the important values of tree layer and herbaceous layer,but there is significant difference on the important values of shrub layer.
