摘　　要：分析重庆万盛黑山自然保护区野生维管植物资源种类、分布及组成结构特征,为该区野生植物资源的保护利用、多样性的维护乃至提升提供依据。采用野外实地样线样方调查、标本采集与鉴定、室内资料查阅整理等方法。结果表明:1)保护区共有野生维管植物172科599属1 331种,其中,被子植物以140科536属1 210种占据优势;2)维管植物单种和寡种科、属数量组成优势突出,单种科和寡种科占总科数62.79%,单种属和寡种属占总属数的92.49%;3)生活型组成上,草本植物有131科355属617种,木本植物有117科258属580种,藤本植物和竹类植物在该区也有分布;4)种子植物属的分布区类型以泛热带分布为主,同时也呈现一定温带特征;5)保护区内国家一级保护野生植物有4种,二级保护野生植物有19种,列入《中国生物多样性红色名录》的植物有48种。从科属、生活型、分布区类型等角度看,万盛黑山自然保护区野生维管植物资源丰富,植物种群组成分散,种子植物兼具温热带特性,植物资源组成结构的稀有性突出。It analyzes the types,distribution,and structural characteristics of wild vascular plant resources in Wansheng Heishan Nature Reserve of Chongqing,providing a basis for the protection and utilization of wild plant resources,maintenance and even improvement of diversity in the area.Methods such as field survey,specimen collection and identification,and indoor data review and organization are used.The results show that:1)There are a total of 1331 species of wild vascular plants in 172 families,599 genera in the Nature Reserve.Among them,1210 species of angiosperms belonging to 536 genera and 140 families dominate.2)The dominant composition of single and few species families and genera in vascular plants is prominent,with single and few species families accounting for 62.79%of the total families,and single and few species genera accounting for 92.49%of the total genera.3)In terms of life form composition,there are 617 species of herbs belonging to 355 genera in 131 families,580 species of woody plants belonging to 258 genera in 117 families.Vines and bamboo plants are also distributed.4)The distribution area type of seed plant genera is mainly characterized by subtropical distribution,while also exhibiting certain temperate characteristics.5)There are 4 first-class protected plants and 19 second-class protected plants in the nature reserve,and 48 plants listed in the Red List of Biodiversity in China.From the perspectives of family and genus composition,life form,and distribution types,the wild vascular plant resources of Wansheng Heishan Nature Reserve are rich,the plant community composition is dispersed,seed plants have both temperate and tropical characteristics.The rarity of plant resource composition structure is prominent.
