江西省野生维管植物名录

为了全面了解江西省野生维管植物资源的现状并为开展相应的生物多样性保护实践提供基础资料, 本文在前人的基础上, 通过进一步的文献收集、标本考证、数据分析, 并结合作者的野外调查结果, 按照维管植物最新的分类系统整理出江西省野生维管植物名录, 并根据标本信息核实了每个物种县市级的分布信息。结果显示, 江西省共有野生维管植物214科1,253属4,761种(含种下等级), 其中石松类与蕨类植物35科103属444种, 裸子植物5科21属36种, 被子植物174科1,129属4,281种。石松类与蕨类植物中, 物种数最多的前5个科为鳞毛蕨科(84种)、水龙骨科(55种)、凤尾蕨科(49种)、蹄盖蕨科(47种)和金星蕨科(47种), 最多的属是鳞毛蕨属(Dryopteris, 40种); 裸子植物中物种数最多的科和属为松科(7属12种)和松属(Pinus, 5种); 被子植物是江西省野生维管植物的最主要组成部分, 分别占科、属、种总数的81.3%、90.1%和89.9%, 其中种数最多的前5个科分别是禾本科(315种)、菊科(241种)、蔷薇科(228种)、唇形科(200种)和豆科(197种), 前6个属依次是薹草属(Carex, 71种)、悬钩子属(Rubus, 66种)、冬青属(Ilex, 56种)、蓼属(Persicaria, 40种)、珍珠菜属(Lysimachia, 37种)和杜鹃花属(Rhododendron, 37种)。江西省维管植物调查呈现出地区不均衡性, 建议增加后续调查工作的广度和深度, 尤其在武夷山脉、赣南山区、鄱阳湖湿地等生物多样性较高或较特殊的地区进行补充采集。同时, 本文呼吁加强专科专属的分类学研究, 为后续名录的修订与完善奠定基础。

A checklist of wild vascular plants in Jiangxi Province,China

Aims: In order to understand the current status of wild vascular plant resources in Jiangxi Province and to provide basic information for the further development of biodiversity conservation, it is necessary to revise and update the checklist of vascular plants in Jiangxi. Method: Based on previous checklists and references, we updated the checklist of wild vascular plants in Jiangxi Province through further historical collections, newly published records and data analysis, as well as the field investigation results conducted by the authors in recent 10 years. The checklist was compiled according to the latest classification of vascular plants, and the distribution of each species at the county and municipal level was verified based on the information of voucher specimens. Results: In total, the present checklist recorded 4,761 species (including infraspecific taxa) belonging to 1,253 genera in 214 families, with 444 species of pteridophytes in 103 genera and 35 families, 36 species of gymnosperms in 21 genera and 5 families, and 4,281 species of angiosperms in 1,129 genera and 174 families. In pteridophytes, the top five largest families of pteridophytes are Dryopteridaceae (84), Polypodiaceae (55), Pteridaceae (49), Athyriaceae (47) and Thelypteridaceae (47), while Dryopteris (40) is the largest genus of pteridophytes. In gymnosperms, the largest family and genus with the highest number of species are Pinaceae (including 7 genera and 12 species) and Pinus (5), respectively. In angiosperms, the top five largest families are Poaceae (315), Asteraceae (241), Rosaceae (228), Lamiaceae (200), and Fabaceae (197), while the top six largest genera are Carex (71), Rubus (66), Ilex (56), Persicaria (40), Lysimachia (37) and Rhododendron (37), respectively. Conclusions: Angiosperms are the main constituent of wild vascular plants in Jiangxi Province with 81.3%, 90.1% and 89.9% proportion of the total families, genera and species, respectively. Meanwhile, vascular plant field surveys in Jiangxi Province showed regional unevenness, we therefore recommend that it is necessary to increase the breadth and depth of follow-up field surveys. Furthermore, we call for the strengthening of specialized taxonomic studies on particular families and genera, which will help to revise and update the checklist further.
