摘　　要：采用线路与标淮地调查相结合的方法,研究了崀山丹霞地貌区森林植物群系特性。结果为:峎山有10个植被型、72个植物群系,其植被主要是中国、日本共同的属和众多的中国特有属树种为组成特征的森林植被,也有一定比例东亚—北美成分,在结构组成上表现出中亚热带常绿阔叶林的特点;丹霞单体出現特异的群系分布格局和"植被孤岛效应",不同发育期丹霞地貌上分布着不同演替系列上的森林植被类型;发現分布于丹霞赤壁下部的1个新的植被型(藤本植被型)和2个丹霞赤壁面上由崀山特有物种为建群种组成的持有植物群系(新宁毛莨群系,崀山唇柱苣苔群系)。The community characteristics of plants in ＂Danxia＂ geomorphological area of Langshan Mountain was researched by the methods of line and quadrat investigation.The results showed that there were 10 vegetation types and 72 formations.The forest vegetation was composed of common genera of China and Japan,endemic genera of China and East Asia and North America element,whose community structure and composition indicated the character of the subtropical evergreen broad-leaved forest.＂Danxia＂ appeared specific community distribution pattern and island effect,and there were different successional series of forest vegetation on ＂Danxia＂ geomorphology at different developmental stages.1 new vegetation type（vine vegetation type） distributed on the lower ＂Danxia＂ bare cliff and 2 endemic plant communities（Ranunculus xinningensis and Chirita langshanica）distributed on the upper ＂Danxia＂ bare cliff were discovered.
