浙江省凤阳山自然保护区蕨类植物区系的研究

A study on the ferns flora in Fengyangshan Nature Reserve in Zhejiang Province

经野外调查和资料整理已知凤阳山自然保护区共有蕨类植物 37科 74属 1 96种和 7变种。主要科为鳞毛蕨科、水龙骨科、金星蕨科、蹄盖蕨科、铁角蕨科、卷柏科、膜蕨科 ,主要属为鳞毛蕨属、铁角蕨属、卷柏属、复叶耳蕨属、瘤足蕨属、凤尾蕨属、瓦苇属。分布区类型以世界分布和泛热带分布科、泛热带分布属、东亚分布种为主 ,表现出亚热带向暖温带过渡的特点。与邻近 6山蕨类植物区系相似性系数的比较表明 ,与凤阳山蕨类植物区系亲缘关系最近的是浙江九龙山。凤阳山共有 5 7种中国特有蕨类 。

The pteridophytic flora of the Fengyangshan Nature Reserve of Zhejiang Province is composed of 196 species and 7 varieties, 74 genera and 37 families. The representative families are Dryopteridaceae, Polypodiaceae, Thelypteridaceae, Athyriaceae, Aspleniaceae, Selaginellaceae and Hymenophyllaceae. The main genera are Dryopteris, Asplenium, Selaginella, Arachniodes, Plagiogyria, Pteris and Lepisorus. The top families’ distribution types are cosmopolitan and pantropic ones; the main genera’s are pantropical ones, while the species distribution type is belong to the East Asia one and represented to the feature of subtropics transition to warm temperated area type. In the 6 reservations, the genetic relationship of Fengyangshan Nature Reserve’s ferns is intimate to Jiulongshan Nature Reserve’s . There are 57 species endemic to China in Fengyangshan Nature Reserve.
