摘　　要：通过野外调查、整理标本室标本以及查看文献资料,分析了毕节国家森林公园蕨类植物区系的地理特征。结果表明,毕节国家森林公园共有蕨类植物27科47属98种。其中优势科为鳞毛蕨科(Dryopteridaceae)、蹄盖蕨科(Athyriaceae)和水龙骨科(Polypodiaceae);优势属为鳞毛蕨属(Dryopteris)、卷柏属(Selaginella)和耳蕨属(Polystichum)。在科属的水平上为泛热带分布型,而种的分布则以温带分布的东亚成分和中国特有成分占绝对优势,所以毕节国家森林公园蕨类植物区系是以泛热带分布和北温带分布为主。Through field survey,collating herbarium specimens,and reviewing historical documents,the floristic geographical features of ferns in Bijie National Forest Park were preliminarily investigated. The results showed that：there are 98 species belonging to 47genera of 27 families. The dominant families are Dryopteridaceae,Athyriaceae and Polypodiaceae and the dominant genus are Dryopteris,Selaginella and Polystichum. The areal-types of families and genera are tropic elements. While the areal-types of species are sub-tropic elements,and the eastern Asia is the main one. It was indicated that Pteridophyte of Bijie National Forest Park is based on pantropical and North temperate.
