摘　　要：云南中南部的哀牢山是生物多样性研究的关键地区之一。根据对该区藤本植物野外调查和标本的采集及鉴定,初步确认有野生藤本植物共60科139属341种或变种,分别占研究区全部种子植物科、属、种的30.15%、14.54%、13.93%。通过对藤本植物种类的组成和地理成分的分析,并与毗邻地区植物区系的比较,哀牢山野生藤本植物区系的种类丰富,起源较为古老,地理成分比较复杂,区系的过渡性质明显。特殊的地理环境,孕育了丰富的野生藤本植物,并且藤本植物生态习性多样,高位芽、茎缠绕藤本植物占绝对优势。通过相似性系数的比较表明,该区藤本植物在科、属、种水平上与无量山的关系最密切。The Ailao Mountains,located in south-central Yunnan,China is one of the key areas for biodiversity research.According to our field investigation and specimens gathering and identification,there are 341 species（including varieties） of seed vines belonging to 139 genera in 60 families,which accounts for 13.93%,14.54% and 30.15% of the whole plant flora in the studied area,respectively.Based on the analysis on species composition and geographical components and comparison with neighboring areas,it is suggested that the flora of wild vines in the studied area has a characteristic of enriched species,ancient origination,complex geographic components,and transitional properties.Specific geographic environments breed enriched wild vines with diverse ecological habits in terms of life forms and climbing types,which are dominated by phanerophytes and stem twiners,respectively.With the comparison of similarity coefficient at family,genera and species levels,the vine flora in the Ailao Mountains has the most closely relationship with that of the Wuliang Mountains.
