| 摘 要： | 分析了桂林岩溶石山桂林白蜡群落的种类组成、区系成分、外貌．结构和物种多样性等特征。组成桂林白蜡群落的维管束植物有52种，隶属38科50属，其中，蕨类植物5科5属5种，裸子植物1科1属1种，被子植物32科44属46种．热带区系成分在群落中占明显优势。群落外貌主要由落叶阔叶中高位芽植物决定。群落的成层现象明显，可分为乔木层、灌木层和草本层；乔木层、灌木层和草本层的物种多样性较低。

| Abstract: | The species composition, flora, physiognomy, structure, species diversity, etc. of Fraxinus guilinensis communities in Karst Hills of Guilin were investigated and characterized. 52 species of vascular plants belonging to 50 genera and 38 families has been found; among them, 5 families with 5 species were ferns, 1 family with 1 species were gymnosperms, and 32 families with 46 species were angiosperm. Tropical floristic elements dominated in the community. The community physiognomy was characterized by the deciduous broad leaved Me.phanerophytes. The community vertical structure could be subdivided into three layers: tree, shrub and herb layer. All the three layers had low species diversity. |
