摘    要:在野外调查和整理资料的基础上,调查分析了古田山自然保护区蕨类植物的区系组成和分布类型,并与邻近的7个山地进行了蕨类植物区系相似性和丰富度的比较.结果表明:古田山共有蕨类植物34科、65属、158种和8变种;主要科为鳞毛蕨科、水龙骨科、金星蕨科、蹄盖蕨科和铁角蕨科,主要属为鳞毛蕨属、铁角蕨属、卷柏属、复叶耳蕨属、瓦韦属和凤丫蕨属.科的分布类型以世界分布和泛热带分布为主;属以泛热带公布为最多;种以东亚分布类型为主,表现出亚热带向暖温带过渡的特点.7个山地中,与古田山蕨类植物区系亲缘关系最近的是浙江九龙山;古田山的蕨类丰富度比纬度位置高的安徽黄山和浙江天目山要大,但比纬度或经度位置低的4个山地小.古田山拥有29种中国特有蕨类及一些珍稀蕨类植物,有较高的保护价值.

关 键 词:蕨类植物  植物区系  统计分析  古田山自然保护区

Abstract:The pteridophytic flora of the Gutianshan Nature Reservation of Zhejiang Province are composed of 158 species and 8 varieties, 65 genera, 34 families. The representative families are Dryopteridaceae (36/4,numbers of species rato to numbers of genera),Polypodiaceae(22/8),Thelypteridaceae(16/8), Athyriaceae(14/4) and Aspleniaceae(11/1) .The main genera are Dryopteris, Asplenium,Selaginella,Arachniodes,Lepisorus and Coniogramme. 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 8 reservations, the genetic ralationship of Gutianshan Nature Reservation's ferns are intimate to Jiulongshan Reservation's .The abundance of Gutianshan's ferns is higher than those of Huangshan and Tianmoshan which have higher latitude, but it is lower than the other nature reservations'. There are 29 species endemic to China in Gutianshan Nature Reservation.
Keywords:pteridophyte  ferns flora  statistical analysis  Gutianshan Nature Reservation  Zhejiang Province
