摘　　要：植物区系研究对于揭示一定区域植被的起源与演化机制具有重要意义,为了探讨我国贵州省梵净山及周边地区藤本植物(被子植物)区系,该研究基于馆藏标本信息、文献资料和野外调查等信息,并运用地理信息系统构建了梵净山地区藤本植物的空间地理分布格局,分析了其物种丰富度及地理分布,同时在全国藤本植物地理分布的背景下,讨论了梵净山地区藤本植物在全国层面的区系特征。结果表明:(1)我国贵州省梵净山地区藤本植物有36科、95属、299个分类群,包含235种、26亚种、38变种,占全国藤本植物66科、268属、1560种的比例分别为54.55%、35.45%、19.17%。(2)梵净山地区藤本植物主要以温带及亚热带地区分布的科属为主,温带成分更为明显。(3)梵净山地区藤本植物在全国范围内主要分布在青藏高原东部、大巴山-巫山地区、武陵山区以及黔桂交界处,对所涉及的藤本植物而言,梵净山地区更多地充当了其分布区的南界。以上研究结果为梵净山地区藤本植物的利用以及今后的保护及监测提供了本底数据,也为植物多样性保护和植物资源的可持续开发和利用提供了科学依据。The study of floristics is essential to reveal the origin and evolutionary mechanism of vegetation in a certain region.Based on the distribution information from specimens,literature and field investigation,we studied the spatial distribution pattern of vines in Fanjing Mountain and its surrounding areas by using ArcGIS,and analyzed the species richness and floristic characteristic under the context of the whole country.The results were as follows:(1)In Fanjing Mountain area of Guizhou Province,299 taxa(including 235 species,26 subspecies and 38 varieties)of vines,belonging to 95 genera,36 families account for 54.55%,35.45%and 19.17%of the total number of 1560 species of vines belonging to 268 genera and 66 families in China,respectively.(2)The analysis of floristic composition showed that the vines of Fanjing Mountain area are mainly composed of temperate and subtropical genera,and the temperate components are more obvious.(3)Under the context of the whole country,the high-richness areas of vines from Fanjing Mountain area are mainly distributed in the east of Qinghai-Tibet Plateau,Daba-Wushan Mountains area,Wuling Mountain area and the junction of Guizhou and Guangxi Province.Therefore,the Fanjing Mountain area is more likely to serve as the southern boundary of their distribution areas.This study provides the background data for the utilization of vines of Fanjing Mountain area as well as their protection and monitoring in the future,and it also provide scientific basis for the protection of plant diversity and the sustainable development and utilization of plant resources.
