The Southern Islands Vascular Flora (SIVFLORA) dataset is a globally significant, open-access resource that compiles essential biodiversity data on vascular plants from islands across the Southern Ocean. The SIVFLORA dataset was generated through five steps: study area delimitation, compiling the dataset, validating and harmonizing taxonomy, structuring dataset attributes, and establishing file format and open access. Covering major taxonomic divisions, SIVFLORA offers a comprehensive overview of plant occurrences, comprising 14,589 records representing 886 species, 95 families, and 42 orders. This dataset documents that 58.62% of the taxa are native, 9.61% are endemic, and 31.77% are alien species. The Falkland/Malvinas Archipelago, the most species-rich, contrast sharply with less diverse islands like the South Orkney Archipelago. SIVFLORA serves as a taxonomically harmonized, interoperable resource for investigating plant diversity patterns, ecosystem responses to climate change in extreme environments, island biogeography, endemism, and the effects of anthropogenic pressures on Southern Ocean flora.
南大洋诸岛维管束植物区系（SIVFLORA）数据集是一项具有全球重要意义的开放获取资源，它汇编了南大洋各岛屿维管束植物的重要生物多样性数据。SIVFLORA数据集通过五个步骤生成：研究区域划定、数据集汇编、分类法验证与统一、数据集属性构建以及文件格式确定与开放获取。SIVFLORA涵盖了主要的分类单元，全面概述了植物分布情况，包含代表886种、95科和42目的14589条记录。该数据集表明，58.62%的分类单元为本地物种，9.61%为特有物种，31.77%为外来物种。物种最为丰富的福克兰/马尔维纳斯群岛与南奥克尼群岛等多样性较低的岛屿形成鲜明对比。SIVFLORA是一个分类统一、可互操作的资源，用于研究植物多样性模式、极端环境中生态系统对气候变化的响应、岛屿生物地理学、特有现象以及人为压力对南大洋植物区系的影响。
