| 为全面掌握湖南省湘西土家族苗族自治州保靖县药用石松类和蕨类植物多样性现状，分析其药用价值并挖掘利用潜能，本研究以野外调查为基础，结合文献资料查阅、标本研究等方法对保靖县药用石松类和蕨类植物物种组成、区系特点、生态学特征及药用价值等方面进行研究。结果表明：(1)保靖县共有药用石松类和蕨类植物27科78属197种，科、属类型较齐全，以鳞毛蕨科Dryopteridaceae、水龙骨科Polypodiaceae和凤尾蕨科Pteridaceae为优势科，以铁角蕨属Asplenium、卷柏属Selaginella、鳞毛蕨属Dryopteris、凤尾蕨属Pteris、铁线蕨属Adiantum、耳蕨属Polystichum、瓦韦属Lepisorus、石韦属Pyrrosia为优势属，科、属内种分布不均匀。(2)保靖县药用石松类和蕨类植物区系具有明显的亚热带性质，属东亚石松类和蕨类植物区系，受热带与温带区系双重影响。(3)药用价值多样，共计11类功效，药用部位以全草、根状茎入药为主。综上所述，保靖县药用石松类和蕨类植物科、属类型较齐全，在系统和进化上较为连贯，具有明显的亚热带性质，资源蕴藏量丰富、产业发展潜力大。 |

| Abstract: |
| To comprehensively understand the current diversity of medicinal lycophytes and ferns in Baojing County,Xiangxi Tujia and Miao Autonomous Prefecture,Hunan Province,and to analyze their medicinal value and potential for exploitation and utilization,this study investigates the species composition,floristic characteristics,ecological traits,and medicinal value of medicinal lycophytes and ferns in Baojing County through field surveys,combined with literature review and specimen research.The results showed that: (1) A total of 197 species belonging to 78 genera and 27 families of medicinal lycophytes and ferns were recorded in Baojing County,with relatively complete familial and generic diversity.The dominant families were Dryopteridaceae,Polypodiaceae,and Pteridaceae,while the dominant genera included Asplenium,Selaginella,Dryopteris,Pteris,Adiantum,Polystichum,Lepisorus,and Pyrrosia.However,the distribution of species within families and genera was uneven.(2) The flora of medicinal lycophytes and ferns in Baojing County exhibits distinct subtropical characteristics and belonged to the East Asian lycophyte and fern flora,being influenced by both tropical and temperate floristic elements.(3) The medicinal values were diverse,encompassing a total of 11 categories of therapeutic effects,with whole plants and rhizomes being the primary medicinal parts used.In summary,the family and genus types of medicinal lycophytes and ferns in Baojing County are relatively complete,and they are more coherent in system and evolution.They have obvious subtropical properties,abundant resources and great industrial development potential. |
