| 摘 要： | 在野外调查基础上,对瑶山苣苔(Dayaoshania cotinifolia)伴生群落进行了研究。结果表明:在4 000m2的样方中,有维管植物208种,隶属于78科147属。群落外貌以小型叶面积、纸质、单叶为主的常绿高位芽植物为特征。群落垂直结构较复杂,成层现象明显,可分为乔木层、灌木层、草本层和层间植物。群落幼苗储备量大,更新良好。瑶山苣苔生存群落表现出较高的物种多样性,各项物种多样性指数排序为乔木层>灌木层>草本层。

| Abstract: | Based on field investigation,the concomitant communities of Dayaoshania cotinifolia were studies.The results suggested that there were 208 species of vascular plants belonging to 147 genera and 78 families in an area of 4000 m2.The appearance traits of communities were dominated by the microphyll,herbaceous and single leaves evergreen phanerophyte.The vertical structure of communities was complex and could be divided into arbor layer,shrub layer,herb layer and interlayer plants.The inventory of seedlings was large and the replacement was good.The level of species diversity of D.cotinifolia communities was higher and the species diversity index ordered as follows: arbor layer > shrub layer > herb hayer. |
