摘要:

中国高等植物多样性编目是“中国生物物种名录”项目中的重要组成部分, 旨在后植物志时代对中国高等植物的物种名录进行修订和年度更新。自2017年深圳国际植物学大会以来, 中国高等植物物种名录已进行了5次年度更新。名录参考最新的植物分类学研究进展, 对各大类群全面采用有分子证据的新分类系统, 收录5年来发表的中国植物新类群和新记录, 补充往年遗漏的部分类群, 并依据新的专科专属的修订结果对发生属间分类变动的类群进行了更新。目前的中国高等植物物种名录包含角苔类4科9属27种, 苔类62科170属1,081种94个种下等级, 藓类94科453属2,006种154个种下等级, 石松类3科12属165种4个种下等级, 蕨类38科177属2,215种228个种下等级, 裸子植物10科45属291种118个种下等级, 被子植物272科3,409属32,708种6,909个种下等级, 共计483科4,275属38,493种7,507个种下等级, 较5年前增加了19科270属2,334种。

Abstract

Aims: Making an inventory of the diversity of Chinese higher plants is an important component of the “Catalogue of Life China” project, which aims to annually update the national checklist of all species found within the country.
Methods: Using recent studies, we adopted the latest understanding of taxonomic classifications of all major plant groups based upon molecular evidence. We then calculated the total numbers of known and new (i.e., those added in the previous five years) taxa across multiple hierarchical classifications, from species up to family. We report the status of the national inventory of plant species as it stands after accounting for recent taxonomic revisions.
Results: Since the 2017 International Botanical Congress (IBC) in Shenzhen, the national checklist has been updated in five instances. The current checklist of Chinese higher plants includes: of the hornworts, four families, nine genera, and 27 species; 62 families, 170 genera, 1,081 species and 94 infraspecific taxa of liverworts; 94 families, 453 genera, 2,006 species and 154 infraspecific taxa of mosses; three families, 12 genera, 165 species and four infraspecific taxa of lycophytes; 38 families, 177 genera, 2,215 species and 228 infraspecific taxa of ferns; 10 families, 45 genera, 291 species and 118 infraspecific taxa of gymnosperms; and 272 families, 3,409 genera, 32,708 species, and 6,909 infraspecific taxa of angiosperms. Higher plants found within the country include a total of 483 families, 4,275 genera, 38,493 species and 7,507 infraspecific taxa. Of these, 19 families, 270 genera and 2,334 species have been added since the 2017 IBC.
Conclusion: The inventory includes the total number of known plant species found within China. Updating of the national checklist in the past five years reflects the most recent studies of plant taxonomy within the country, promotes the progress of a global effort to inventory biodiversity, and provides detailed baseline data for flora collections, biodiversity research, and conservation practices.
