对太白山自然保护区蕨类植物区系进行了初步的研究.结果表明：太白山共有蕨类植物21科、39属、110种，并且优势科属明显，蹄盖蕨科、鳞毛蕨科、水龙骨科为优势科，卷柏属、铁线蕨属、耳蕨属、瓦韦属、鳞毛蕨属、铁角蕨属为优势属；科的地理分布主要以世界分布为主，占该区总科数的47．6％，属的分布以温带成分为主，占总属数的58．3％，种的地理分布也以温带分布为主，占总种数的48．2％；该区在地理亲缘关系上与河南伏牛山和陕西化龙山最为密切，与四川唐家河、山西五鹿山、北京松山、河北茅荆坝、湖北神农架为其次，与湖南壶瓶山、甘肃祁连山较为疏远，与宁夏南华山的的联系最为疏远.

Pteridophyte floras in Taibaishan Natural Reserve were studied,and the results were as follows:there were 110 species of ferns belonging to 39 genera and 21 families.The dominant families and genera were obvious.In the area,the dominant families were Athyriaceae,Dryopteridaceae,Polypodiaceae and the dominant genera were Selagi-nella,Adiantum,Polystichum,Asplenium,Dryopteris and Lepisorus.The families geogrophical elements belonged to world distribution accounting for 47.6% of the total in this area,the general geogrophical elements were dominan-ted by temperate composition occupying about 58.3% of all the generals and the species′covers also temperate com-position with the proportion of 48.2% in all.On the aspect of geographical kinship,they were closely related to Fu-niushan in Henan and Hualongshan in Shaanxi,less closely with Tangjiahe in Sichuan,Wulushan in Shanxi,Songshan in Beijing,Maojingba in Hebei,Shennongjia in Hubei,and had a distant relation to Hupingshan in Hunan,Qilianshan in Gansu,ultimately,the farhermost one is Nanhuashan in Ningxia.
