陕西省维管植物名录(2021版)

陕西省位于黄土高原和秦巴山区的核心地带, 复杂多样的生态地理环境孕育了丰富的植物种类。为了及时总结并展现陕西省植物物种多样性与分布信息, 基于已公开发表的论著, 本文更新构建了2021版陕西省维管植物名录。结果表明, 陕西省野生、归化及栽培维管植物有5,161种及种下分类群, 包含209科1,316属4,701种, 种下分类群有112亚种488变种17变型。物种数比上一版名录增加了214种, 主要是近年来发现的新分布野生植物, 也有少量的新物种和外来入侵植物。新版名录中科的范围界定与编排采用了以分子系统学结果为主要依据的新的分类系统, 并以Excel格式数据集的形式发表, 便于公众获取并检索利用。本文建议应持续开展野外考察工作, 尤其是加强对巴山地区的调查, 对外来入侵植物的监测也不容忽视。

A checklist of vascular plants in Shaanxi Province,China (Version 2021)

Aim: Shaanxi Province is located in the core areas of the Loess Plateau and the Qinling-Bashan Mountains in China. The diverse ecological and geographical environment harbors a rich plant diversity in Shaanxi. It is important to document and to emerge the species diversity and geographical distribution of the vascular plants in Shaanxi. Method: Based on the summary of published literatures, we updated the checklist of vascular plants in Shaanxi Province, China. Results: A total of 5,161 species and infraspecies taxa of wild, naturalized, and cultivated vascular plants were presented in this checklist, which belonging to 209 families, 1,316 genera, 4,701 species with 112 subspecies, 488 varieties, and 17 forms. A total of 214 species was supplemented comparing with the last version of the checklist, dominated by new records of wild plants in Shaanxi in recent years. New species and newly reported alien invasive plants also accounted for a small number. In this new checklist, the delimitations and arrangements of plant families follow new systems that largely based on molecular phylogenetics. An online dataset of the checklist in the Excel format is available to the public, making the acquirement, retrieval and utilization of the data smooth. Conclusions: Our results show that continuous field surveys is still important in Shaanxi. Investigations into the Bashan Mountains should be promoted. The watch on the alien invasive plants should not be neglected.
