摘　　要：为保护利用野生药用藤本植物资源,通过野外实地调查、标本采集和逐一考证方式,对湖南云山野生药用藤本植物资源进行了全面系统的调查研究。结果表明:湖南云山共有野生药用藤本植物44科107属272种,分别占该区维管束植物科、属和种的21.67%、9.87%和17.92%,其中蕨类植物1科1属1种,裸子植物1科1属1种,被子植物42科105属270种。在被子植物中,双子叶藤本具有明显的优势,有39科101属249种;单子叶藤本仅有3科4属21种。在云山野生药用藤本植物中科的构成比较集中,属的构成相对分散。在攀援方式上,缠绕藤本具有优势,占总种数的48.53%;卷曲类、搭靠类和吸固类较少,分别占总种数的21.32%、19.49%和10.66%。区系组成以热带分布类型为主,热带分布属共有71属,占总属数的66.36%;有国家级稀有濒危保护植物1种,国家重点保护野生植物12种,第一批国家重点保护野生药材2种。在药用部位上,以根、叶和根茎的药用藤本植物最多,分别占65.44%、29.78%和27.57%;在药用功效上,以祛风湿、活血化瘀和清热类最多,分别占52.21%、50.00%和45.22%。同时,对云山野生药用藤本植物资源的保护和开发利用提出了建议。The wild medicinal liana resources in Hunan Yun maintain was investigated by field survey, sample collection and identification methods systematically.Results：There are 272species,107genera,44 families,accounting for 17.92%,9.87%,21.67% of species,genera,family in vascular plants respectively.Of which,there are 1species,1genus,1family for fern,1species,1genus,1family for gymnosperm and 270species,105genera,42families for angiosperm.There are 249species,101genera, 39families for dicotyledon and 21species,4genera,3families for monocotyledon in angiosperm.The family＇s composition is concentration but genus＇ s composition is dispersion relatively.The proportion of twining,curling,hooking and adhering liana is 48.53%,21.32%,19.49% and 10.66% respectively. There are 71tropical genera,accounting for 66.36% of total genera.1species,12species and 2species belong to National Rare and Endangered Plant,National Wild Plants and First National Wild Herbs separately.The root,leaf and rhizome of medicinal liana account for 65.44%,29.78% and 27.57% respectively according to medicinal parts.The root,leaf and rhizome with antirheumatic,blood circulation and antipyretic medicinal function account for 52.21%,50.00%and 45.22%separately.The suggestions for protection and development of medical liana resources are put forward in the paper.
