摘要
在野外调查和资料整理的基础上,调查分析了雷公山自然保护区蕨类植物Pteridophyte的区系。结果表明,雷公山国家级自然保护区共有蕨类植物42科、91属、267种(含9变种);含10个种以上的科有鳞毛蕨科Dryopteridaceae、水龙骨科Polypodiaceae、蹄盖蕨科Athyriaceae、铁角蕨科Aspleniaceae、金星蕨科Thelypteridaceae、膜蕨科Hymenophyllaceae、卷柏科Selaginellaceae。依据植物的现代地理分布,雷公山自然保护区蕨类植物种的分布可以划归11个分布区类型和8个亚型,其中东亚成分和热带亚洲成分构成其区系的主体。区系分析表明,该地区蕨类植物处于东亚植物区系中,但热带亚洲成分对本区也有一定影响,表现为亚热带向温带过渡的特点。
The results showed that there were totally 42 families ,91 genera,267 species （ included 9 varieties） of Pteridophyte in Mt. Leigongshan Nature Reserve. The families which included more than 10 species were Dryoptefidaceae, Polypodiaceae, Athyriaceae, Aspleniaceae, Thelypteridaceae, Hymenophyllaceae and Selaginellaceae. The Pteridophyte species in Mt. Leigongshan Nature Reserve can be divided into 11 areal-types and 8 subtypes. Temperate distribution and Tropical Asia distribution were the main elements of the areal-type in this area and represented the feature of subtropics transition to temperate arealtype.
