摘　　要：为了解世界维管植物新物种的基本信息,明确生物多样性面临的威胁,总结未来研究方向,本文对2020年世界维管植物新物种的数据进行了统计分析。根据国际植物名称索引(IPNI)的记录,截至2021年2月1日,2020年全球发现1,747种维管植物新种,由1,544名植物学家(264位中国植物学家,1,280位国外植物学家)发表在103种期刊和5本书中。1,747种维管植物新种包括被子植物1,689种、蕨类植物52种、裸子植物6种。其中大部分来源于维管植物最大的几个科,例如菊科、兰科和胡椒科。植物学家描述的美洲南部和热带亚洲维管植物新种超过828种,是2020年维管植物新种发现最重要的两个地区。中国、巴西和马达加斯加是2020年贡献维管植物新种最多的前三位,分别有247、223、99个新种。值得关注的是,Phytotaxa和Phyto Keys是2020年发表维管植物新种的主要期刊,分别发表644种和168种。在各物种新名称中,有5个无效名称和2个不合法名称。尽管近年来对生物多样性的关注日益增加,但世界上仍有许多物种尚未被发现,需要对各个地区植物进一步调查和研究,尤其是生物多样性热点地区和岛屿地区。Aims:Research and publication of the planet’s remaining plant species as yet unknown to science is essential if we are to address the United Nations Sustainable Development Goal(SDG)15"Life on Land"which includes the protection of terrestrial ecosystems and halting of biodiversity loss.If species are not known to science,they cannot be assessed on the International Union for Conservation of Nature(IUCN)Red List of Threatened Species,and thus reducing the possibility to protect them from extinction.Scientific discovery,including naming new taxa,is important because without a scientific name,a species is invisible to science and the possibilities of researching its ecology,applications,and threats,and conserving it,are greatly reduced.This study analyzes the new species of vascular plants in the world published in 2020,aims to enrich the basic information about the new species of vascular plants in the world,discuss the current threats to biodiversity,and summarize the direction of future research.Methods:The data were derived from the International Plant Name Index(IPNI;https://www.ipni.org/).Statistics of new species of vascular plants published in 2020 were available as of February 1,2021 excluding new combinations,new statuses or new names and bryophyte data.In order to facilitate the comparison of new species of vascular plants discovered and published in major regions and countries in 2020,the data in this article were only from IPNI,although IPNI had not documented all new species published in 2020 by February 1,2021,and those species published in some local journals(such as university journals)and local monographs were not available in IPNI.Results:In 2020,1,747 new species of vascular plants were described worldwide in 103 journals and 5 books by 1,544 botanists(264 Chinese botanists,1,280 non-Chinese botanists),as documented in IPNI.Among the 1,747 new species,1,689 belonged to angiosperms,52 to pteridophytes,and only 6 to gymnosperms.A large number of new species were from the largest families,such as
