摘 要：
为了解贵州从江含笑产地的群落特征,为其保护和相关研究提供科学依据,采用样方调查法,分析从江县光辉乡加牙村从江含笑天然群落的物种组成、外貌特征和结构特征,并计算乔木层的物种多样性。结果表明:从江县光辉乡加牙村从江含笑天然群落植物共有16科22属23种,其中热带分布类型的属有13属,占总属数的61.9%;高位芽植物20种,占86.9%。群落垂直结构明显,分为乔木层、灌木层和草本层,从江含笑的重要值为79.18,群落的物种多样性指数一般,物种相对较少;群落以从江含笑和水青冈为建群种,群落结构稳定。

摘 要：
The species composition,appearance feature and structure characteristics of natural M.chongjiangsis community in Jiaya Village,Guanghui Township,Congjiang County were analyzed by the sample plot survey method and the species diversity of tree layer in natural M.chongjiangsis community was calculated to understand the community characteristics of M.chongjiangsisin Guizhou and provide the scientific basis for protection and correlation research of M.chongjiangsis.Results:There are23 species,22genera,16 families in natural M.chongjiangsis community.13 genera with the tropical distribution type account for 61.9% of total genera and 20 phanerophytes account for 86.9%.The M.chongjiangsis community with an obvious vertical structure can be divided into tree layer,shrub layer and herb layer.The importance value of M.chongjiangsis is 79.18.The species diversity index of tree layer in M.chongjiangsis community is not high,which indicates that species are less relatively.The structure of M.chongjiangsis community with the constructive species of M.chongjiangsis and Fagus longipetiolata is stability.
