海南省野生维管植物编目和分布数据集

A dataset on inventory and geographical distributions of wild vascular plants in Hainan Province,China

海南省是我国热带雨林连片面积较大的地区,是我国物种多样性最为丰富的生物多样性关键地区之一,关于海南省植物编目的工作在2012–2015年间就取得了较好的进展,陆续出版了《海南植物物种多样性编目》《海南植物名录》和《海南植物图志》。但是随着对海南植物研究的深入,原来所记录的一些维管植物类群经过分类修订后名称发生了变化,科属分类及其名称需要进行调整,同时原来所采用的分类系统也亟需更新。本文在《海南植物名录》和《海南植被图志》的基础上,结合历年实际野外调查经验,通过系统检索文献资料和查阅相关书籍对现有编目数据进行查漏补缺,修订名称、更新分类系统,完善植物分布区、保护等级状况等相关信息,最终完成海南省野生维管植物编目和分布数据集。截至2023年2月,该数据集共有数据4,945条,其中包括石松类植物2科6属39种,蕨类植物32科121属531种,裸子植物6科10属27种,被子植物181科1,380属4,348种;数据集中列入《国家重点保护野生植物名录(2021)》的有173种(其中一级8种,二级165种);本土野生植物共有216科1,448属4,769种(含海南特有植物516种),外来逸生及归化植物有176种(含入侵植物63种)。与2013年出版的第一版《海南植物名录》相比,野生维管植物总物种数增加225种。本数据集可作为海南省维管植物多样性监测和保护的重要基础数据。

Hainan Province is an area with a large contiguous area of tropical rainforest in China.It is one of the key areas of biodiversity with the largest tropical rainforest area and the most abundant species diversity in China.During 2012–2015,the Inventory of Plant Species Diversity of Hainan,List of Species in Hainan,and Illustrated Handbook of Plants in Hainan were published in succession.The progress of related cataloging is relatively advanced in China.However,with the in-depth study of Hainan plants,the names of some vascular plant taxa originally recorded have changed after new taxonomic revision.The classification of families and genera and their names need to be adjusted.At the same time,the original classification system also need to be updated.Based on the List of Species in Hainan and Illustrated Handbook of Plants in Hainan,combined with experience from many years of practical field investigation,we systematically searched the literature to fill the gaps in the existing catalog data,checking for omissions and deficiencies.The name was revised,the classification system updated,and relevant information such as plant distribution areas and protection levels improved.Finally,the cataloging and distribution dataset of wild vascular plants in Hainan Province was complete.As of February 2023,the dataset had 4,945 records,including 39 species of lychophytes belonging to 6 genera of 2 families;531 species of ferns belonging to 121 genera of 32 families;27 species of gymnosperms belonging to 10 genera of 6 families,and 4,348 species of angiosperms belonging to 1,380 genera of 181 families.Among them,there were 173 species listed in the List of National Key Protected Wild Plants(2021)(8 species in the first class and 165 species in the second class);there were 4,769 species of native wild plants belonging to 1,448 genera and 216 families(including 516 endemic species of Hainan)and 176 species of exotic and naturalized plants(including 63 invasive species).Compared with the first edition of the List of Species in Hainan,the total number of wild vascular plants increased by 225 species.This dataset can be used as important basic data for vascular plant diversity monitoring and protection in Hainan Province.
