摘　　要：以野外实地调查、标本采集和文献资料分析相结合的方法,对金洞国家森林公园藤本植物的资源种类、区系地理成分、生态特征及园林应用进行了系统研究。结果表明:(1)该区藤本植物共计有48科107属238种(含变种),科种数分别占该区维管植物科、种的22.86%、15.29%,其中蕨类植物有2科2属2种,双子叶植物43科101属212种,单子叶植物3科4属24种。(2)该区植物区系成分复杂,以热带性分布为主,其中泛热带分布最多,占到了属总数的25%,出现了海南链珠藤、大花帘子藤等严格热带区系成分的藤本。(3)该区缠绕类藤本占优势,共计110种,占总数的46.22%,卷曲类、搭靠类、吸固类种类较少,分别占总数的24.79%、19.33%和9.66%。(4)该区观赏性藤本植物有较多种类,通过在长沙的引种试栽与观察,重点推荐中南鱼藤、粉叶羊蹄甲等32种具有一定观赏价值的藤本植物作为城市园林绿化应用参考。We conducted a systematic research on the types of resources,geographical element,ecological characteris-tics and landscape application of liana in Jindong National Forest Park,by means of field investigation,sample collection and related references.The study results show that：（1）There are 48 families,107 genera and 238 species （including varieties）of liana in this area,accounting for 22.86% and 15.29%,respectively of families and species of vascular plants in the same region.Among all these liana,there are 2 families,2 genera and 2 species of pteridophyte,43 fami-lies,101 genera and 212 species of dicotyledonous,and there are 3 families,4 genera and 24 species of monocotyledon-ous.（2）The floristic composition is complicated,mainly tropic,and pantropic plants have the most genera,account-ing for 25% of overall genera.There are some strict tropical liana,such as Alyxia hainanensis and Pottsia grandiflora. （3）In terms of climbing style,the majority is twining liana,a total of 110 species,accounting for 46.22% of overall species,while the minorities include curling,hooking and adhering liana,accounting for 24.79%,19.33% and 9.66% of overall species,respectively.（4）There are more kinds of ornamental liana in the area,through the intro-duction of test plant and observation in Changsha,32 species such as Derris fordii,Bauhinia glauca,are strongly recom-mended,which have ornamental value and as a reference for urban landscape application.
