摘要: 野含笑为我国省级珍稀濒危植物。通过对野含笑群落的特征进行分析和研究,结果表明:野含笑群落植物种类丰富,科属组成分散,区系成分复杂。从属的地理成分来看,热带分布的属明显多于温带分布的属。群落的生活型以高位芽植物为主,地面芽植物次之。该群落叶的性质以小型叶、单叶、革质、非全缘为主。群落垂直结构复杂,地上成层明显,可分为乔木层、灌木层和草本层,并有一定数量的层间植物。灌木层→乔木层→草本层物种多样性依次递减。野含笑种群的年龄结构属稳定型。Abstract: Michelia skinneriana is a rare plant.The study on the feature of M.skinneriana community showed that:There are various plants in the community of M.skinneriana,and its family and genus are of scattered compositions.Their floral composition is complicated.In terms of genus geographical elements,many of them are distributed in tropical zones.According to Raunkiaer's statistics of life-form,the life-form phaenerophyte of this community numbers first,and the hemicryptophyte second.The features of the community leaf is mainly microphyll,simple,leathery and unentire.The vertical structure of community is relatively complicated which can be divided into tree layer,shrub layer and herb layer as well as a definite number of interstratum plants.The species diversity decreases from shrub,tree to herb layer.The age structure of M.skinneriana is stationary.
