【摘要】 广东省高等植物物种多样性位居全国第六。本研究依据植物志、植物图鉴、保护区植物名录、期刊文献、学位论文等文献资料,并结合标本数据和中国植物图像库的图片,以及作者的野外调查,编制了广东省高等植物多样性名录和县市级分布数据集。本数据集的每一条记录即为一个分类群在某个具体县市级的分布。截至2023年7月,本数据集收录广东省高等植物72,279条分布记录,共计374科2,284属8,106种(含种下等级)。广东省本土野生高等植物350科1,828属6,864种,其中苔藓植物(包括角苔类、苔类和藓类)96科272属865种,石松类和蕨类植物36科123属642种,裸子植物7科17属35种,被子植物211科1,416属5,322种,有17种为广东省新分布种。种数最多的前10科依次是禾本科、豆科、兰科、莎草科、茜草科、唇形科、菊科、蔷薇科、樟科和苦苣苔科。本数据集也收录了广东省入侵植物58科204属323种、归化植物62科206属257种,以及常见栽培植物129科441属662种。另外,本研究还提供了一个广东省高等植物分布存疑或排除的物种名单,共182科545属905种,供后续进一步研究。本文数据将为《广东植物志》第二版的编撰提供基础资料和系统框架。更多还原

【Abstract】 Guangdong Province has a rich diversity of higher plants, ranking it sixth in China. This study compiles an updated dataset of higher plants with county-level records in Guangdong Province by drawing from sources including floras,illustrated plant books, nature reserve plant checklists, academic papers, dissertations, specimens, photos from the Plant Photo Bank of China, and our own field surveys. The resulting dataset details distributions of various taxa in specific counties and cities. As of July 2023, this dataset contains 8,106 taxa from 374 families and 2,284 genera of higher plants in Guangdong. Native wild higher plants account for 6,864 taxa from 350 families and 1,828 genera, where bryophytes(including hornworts, liverworts and mosses) makeup 865 taxa from 96 families and 272 genera, lycopods and pteridophytes account for 642 taxa from 36 families and 123 genera, gymnosperms total 35 taxa from 7 families and 17 genera, and angiosperms makeup 5,322 taxa from 211 families and 1,416 genera. In addition, 17 species are here reported new to the Guangdong Province. The families with the largest number of species are Poaceae, Fabaceae,Orchidaceae, Cyperaceae, Rubiaceae, Lamiaceae, Asteraceae, Rosaceae, Lauraceae and Gesneriaceae. This dataset also includes 323 invasive species from 58 families and 204 genera, 257 species of naturalized plants from 62 families and 206 genera, and 662 species of common cultivated plants from 129 families and 441 genera. Furthermore, this study provides a list of higher plants with excluded and dubious records; this list encompasses includes 905 species from 182families and 545 genera. This dataset will provide foundational information and a framework for the second edition of Flora of Guangdong.更多还原
