摘要: 初步探讨了广东阳春鹅凰嶂自然保护区蕨类植物区系的地理特点,结果表明:本区有蕨类植物134种(包括变种与变型),隶属于38科72属,优势成分以水龙骨科、金星蕨科、鳞毛蕨科等系统演化上较高级的类群为主。区系单种属较多,起源古老,地理成分复杂,但热带、亚热带成分占主导地位。这些区系特征与本区古老的地质和优越的水热条件密切相关。

Abstract: The floristic phytogeographical features of the ferns and fern allies in the Mt.Ehuangzhang Nature Reserve are discussed.There are about 134 species (including varieties and forms) of pteridophytes belonging to 72 genera and 38 families in this area,and the higher taxa in system and evolvement,such as Polypodiaceae,Thelypteridaceae and Dryopteridaceae are the dominent.Through the analysis the additional results are as follows:Rich in single species families,ancient in origin,complexion,varied in geographical elements,having an extensive connection with nearby floristic areas,but dominating in tropical and subtropical elements.It is nearly correlative with the ancient geologic structure and ascendant natural condition here.
