以江西武夷山国家级自然保护区核心区为无干扰环境，选取河岸带、内陆森林和林线3种生境阔叶林群落为研究对象。群落结构特征分析结果显示：1）不同生境类型的群落建群种不同，但群落各层主要优势种的重要值均呈差异不显著，物种组成上均以壳斗科、樟科、山茶科、山矾科、杜鹃花科、蔷薇科、冬青科等为常见，且种属数较多。2）立木总株数（乔灌木）林线群落高于其他生境群落，但不同生境类型的群落间乔木与灌木平均株数均呈差异不显著。3）群落各层物种的种数及各物种多样性指数均有河岸带>内陆森林>林线，乔木层、草本层与层间植物物种种数以及物种多样性Patrick、Gleason、Margalef和Shannon-Weiner指数，河岸带均与其他生境类型群落差异呈显著性；而灌木层物种种数及多样性Simpson和Pielou指数差异不呈显著性。4）散点图和线性回归得出林线群落活立木平均高度和平均胸径均高于其他生境类型的群落。

In core area of Jiangxi Wuyishan National Nature Reserve, as the non-disturbance condition, three habitats broad-leaved community of riparian zone, inland and forest line were selected for study aspects. Community structure characteristics analysis results showed that: 1) there were different constructive species of the community in different habitats, but the important value of the main dominant species in the communities’ layers has no significant difference. Species composition dominated by Fagaceae, Theaceae, Lauraceae, Symplocaceae, Ericaceae, Rosaceae, Aquifoliaceae with much of genera and species in all types of the habitats. 2) The total number of the standing timber (including trees and shrubs) in the forest line community was more than other communities, but the average number of the trees and shrubs in different habitats has no significant difference. 3) Community species and each species diversity index were riparian zone>inland forest>forest line. The tree layer, herb layer and interlayer plants species number and Patrick, Gleason, Margalef and Shannon-Weiner index in riparian zone were significantly different from other habitat type communities. But the shrub layer species number and Simpson and Pielou index showed no significant difference in different habitats. 4) The scatter diagram and the linear regression showed that the average height and average DBH in the forest line community were greater than other habitats communities.
