摘　　要：【目的】更好地开发利用野生藤本植物资源,丰富城市绿化美化的植物类群。【方法】采用样地与样线相结合的调查方法,对秦岭地区藤本植物的种类组成、地理分布区类型、攀援方式等进行了研究。【结果】(1)秦岭地区藤本植物种类丰富,共计36科98属285种,分别占本区种子植物科、属、种的18.18%,9.73%和8.27%,其中木质藤本164种,草质藤本121种;单子叶植物17种,双子叶植物268种。(2)秦岭地区藤本植物属有13个分布区类型,而热带性地理成分居首位,占53.84%。(3)秦岭地区藤本植物攀援方式有4大类,以缠绕类为最多,占50.53%;其次为卷须类和钩刺类,分别占31.23%和13.33%,吸附类藤本种类最少,只有4.91%。【结论】秦岭地区藤本植物资源丰富,开发利用潜力巨大,加强对野生藤本植物的引种驯化,可以丰富城市园林植物的多样性。[Objective] The aim of this study was to develop and utilize wild vines resources,and to rich the varieties for urban greening. [Method] Sample plot method and line intercept method were adopted to study the families/genera,floristic elements, and climbing types of vines in Qinling Mountains. [Result] （1） A total of 285 spermatophyte species belonging to 36 families and 98 genera in Qinling Mountains were found,including 164 timber vines and 121 herbaceous vines （17 monocotyledon plants and 268 dicotyledon plants）. The contributions of vines to total family, genus, and species of local seed plants were 18.18%, 9.73%, and 8.27% ,respectively. （2） Based on {loristic elements analysis,vines genera could be divided into 13 regional types, and tropical floristic elements were dominant in Qinling Mountains, accounting for 53.84~ to all genera. （3）There were four vines climbing types.twining accounted for 50.53% ,curling ac- counted for 31.23% ,hooking accounted for 13.33% and adhering accounted for 4.91%. [Conclusion] Qin- ling Mountains are rich in wild vines resources with great potential for exploitation. The landscape plants could be enriched by introducing more wild vines from Qinling Mountains.
