浙江箬寮岘自然保护区蕨类植物区系研究

Studies on the Pteridophyte Flora of Ruoliaoxian Nature Reserve in Zhejiang Province

箬寮岘自然保护区有蕨类植物38科69属153种(包括亚种和变种),其中优势科是鳞毛蕨科、水龙骨科、金星蕨科、蹄盖蕨科、铁角蕨科、卷柏科,优势属是鳞毛蕨属、铁角蕨属、卷柏属、复叶耳蕨属、凤尾蕨属和短肠蕨属。属的分布类型以泛热带分布最多;种类以东亚分布类型和特有成分为主,表现为亚热带向暖温带过渡特点。在区系关系上,该区系与九龙山、古田山、天目山、庐山、武夷山区系关系密切,而与苍山、西山、太行山、帽儿山区系关系较为疏远。区系属于东亚植物区系。

The pteridophyte flora in Ruoliaoxian Nature Reserve are composed of 153 species（including varieties and subspecise）,69 genera,38 families.Comparing with nine florae,the integratiye coefficient of this flora（0.161） is the fifth.The representative families are Dryopteridaceae,Polypodiaceae,Thelypteridaceae,Athyriaceae,Aspleniaceae and Selaginellaceae.The main genera are Dryopteris,Asplenium,Selaginella,Arachniodes,Pteris and Allantodia.The main genera＇s distribution types are pantropical ones,while the species distribution types is belong to the east Asia one and represented to the feature of subtropics transition to warm temperated area-type.In the ten relevant mountainous regions,the floristic elements of this flora are similar to those of Mt.Jiulongshan,Mt.Gutianshan,Mt.Tianmushan,Mt.Lushan and Mt.Wuyishan,but this flora has the closest relationship with that of Mt.Jiulongshan and Mt.Gutianshan.
