摘　　要：利用群落学方法对浙江省泰顺县黄连山村的毛枝连蕊茶Camellia trichoclada群落结构与物种多样性进行分析研究。结果表明:该群落植物资源丰富,共有维管植物58科104属153种。按Ruankiaer生活型统计,高位芽植物占85.0%,地上芽植物占2.6%,地面芽植物占13.1%,隐芽植物占8.5%,1年生植物占0.7%。群落结构可分为乔木层、灌木层和草本层。灌木层丰富度指数(S),Simpson指数(D)和Shannon-Wiener指数(H)均最大,分别为95,5.585 9和0.966 9;乔木层的分别为14,2.285 5和0.770 5;草本层为:38,3.845 9和0.870 5。乔木层的均匀度指数最大,为1.275 5,而灌木层和草本层次之,分别为1.226 6和1.057 3。A survey of community structure and species diversity of Camellia trichoclada in Huanglian village,Taishun County of Zhejiang Province was conducted through quadral sampling.Results showed that there were 58 families,104 genera,and 153 species of vascular plants.According to Raunkiaer＇s classification,phanerophytes accounted for 85.0 per cent,chamaephytes 2.6 per cent,hemicryptophyta 13.1 per cent,cryptophytes 8.5 per cent and therophytes 0.7 per cent.The community could be divided into three layers including trees,shrubs and herbs with the highest species richness（S）,Simpson＇s（D）,and Shannon-Wiener＇s（H） indices in the shrub layer followed by the tree and herb layers.Shrub indices were S=95,D=5.585 9,H=0.966 9;tree indices were S=14,D=2.285 5,H=0.770 5;and herb indices were S=38,D=3.845 9,H=0.870 5.The evenness（J）indices of the tree layer were largest（1.275 5）,followed by the shrub（1.226 6）and herb layers（1.057 3）.
