| 摘 要： | 安徽祁门地区蕨类植物共有107种(包括变种、变型),隶属于28科56属,其中发现安徽地理分布新记录种1个,即丝带蕨(Drymotaenium miyoshianum).该区的蕨类植物优势科为鳞毛蕨科(Dryopteridaceae)、水龙骨科(Polypodiaceae)和蹄盖蕨科(Athyriaceae);优势属为鳞毛蕨属(Dryopteris)、卷柏属(Selaginella)和复叶耳蕨属(Arachniodes).属的地理成分以泛热带为主,亚热带和温带分布次之;种的地理分布则以中国-日本分布和中国特有分布为主.祁门蕨类植物区系在区系区划上应属于典型的华东地区.该区的蕨类植物生态类型以土生为主.种的相似性分析和属的聚类分析表明:该区系与三清山和天童山的关系密切,而与白石砬子等关系疏远.

| Abstract: | There are 107 species(including varieties,forms) which belong to 54 genera and 26 families in Qimen Region,Anhui Province.Among them a species,Drymotaenium miyoshianum is first recorded.The predominant families in Qimen region are Dryopteridaceae,Polypodiaceae,Athyriaceae;predominant genera are Dryopteris,Selaginella,Arachniodes.Based on the analysis of geographic elements of genera,the result shows that the pan-tropical elements are dominant,but of species,East-Asia elements including China-Japan and Chinese endemic elements are dominant.Qimen region is a key area of East-China flora.The pteridophyte of Qimen can be grouped into 4 distribution types,and of them the terrestrial ecological group is dominant in 107 species.According to similarities of species and cluster analysis of genera,this flora is much closely allied to Sanqing Shan and Tiantong Shan than the other areas,such as Baishilazi Nature Reserve,etc. |
