摘　　要：为摸清广西泗水河自治区级自然保护区维管植物资源现状,采取全面踏查、样线及样方调查相结合的方法对该保护区维管植物多样性进行调查,分析其物种组成和区系特征。结果表明,广西泗水河自然保护区共有维管植物184科634属1022种,其中蕨类植物31科58属81种,种子植物153科576属941种;维管植物科的组成以少种科和单种科占比最多,共占维管植物总科数的83.15%;国家重点保护野生植物15种;外来入侵植物10种。广西泗水河自然保护区维管植物区系地理成分丰富复杂,以热带分布科和热带分布属占据优势,说明该区域植物区系具有较明显的热带性质,反映了南亚热带植物南缘地带区系地理成分的特点。In order to understand the current status of vascular plant resources in Guangxi Sishuihe Regional Nature Reserve,a survey on the diversity of vascular plants in the reserve was conducted using a combination of comprehensive investigation,line transect and quadrat survey,and the species composition and floristic characteristics were analyzed.The results showed that there were a total of 1022 vascular plant species belonging to 634 genera and 184 families in the Sishuihe Nature Reserve,including 81 fern species belonging to 58 genera and 31 families,and 941 seed plant species belonging to 576 genera and 153 families.The composition of vascular plant families is dominated by families with few species and single-species families,accounting for 83.15%of the total number of vascular plant families.There were 15 species of national key protected wild plants and 10 species of invasive alien plants.The floristic composition of vascular plants in the Sishuihe Nature Reserve is rich and complex in geographic elements,with tropical distribution families and genera being dominant,indicating a significant tropical nature of the plant flora in the Sishuihe Nature Reserve,reflecting the characteristics of the floristic geographic composition in the southern edge zone of the South Asian tropical plants.
