摘要/Abstract

摘要：

生物多样性研究的基础是准确地描述现有物种并清楚地统计物种数量。为了全面了解河北省苔藓植物多样性的研究现状, 本文基于课题组多年来的研究成果, 结合相关文献, 整理出河北省苔藓植物最新名录, 并对苔藓植物物种组成、区系特征、动态变化以及受威胁情况等进行了初步分析。到目前为止, 河北省苔藓植物有76科190属544种。其中, 藓类植物51科152属468种; 苔类植物24科37属75种; 角苔类植物1科1属1种。≥ 15种的优势科有8科, ≥ 10种的优势属有12属。河北省苔藓植物区系表现出温带成分比例高于热带成分, 北温带成分占优势的特点。中国特有种共计33种, 濒危(EN) 4种, 易危(VU) 5种。与《河北高等植物名录》相比, 本名录新增补苔藓植物10科34属162种, 移除了9种, 修订了86个物种学名。提灯藓科、丛藓科、青藓属(Brachythecium)、真藓属(Bryum)等科属代表了新增补苔藓植物的主要类群。河北省苔藓植物物种多样性较为丰富, 其调查呈现出区域不均衡性; 今后应重视秦皇岛、唐山、邯郸等苔藓植物调查薄弱地区的工作, 并加强名录修订。另外, 在全球气候变化的大背景下, 要及时关注苔藓植物的动态变化, 以期为河北省苔藓植物物种多样性研究及保护提供科学依据。

Abstract

Aims: The foundation of biodiversity study is the accurate description of existing species and a clear enumeration of their numbers. A comprehensive checklist is the basic data for understanding and conserving biodiversity within a specific region. To thoroughly understand the current status of bryophyte diversity in Hebei Province, it is important to revise the list of bryophytes in the province.
Method: Based on our team’s research findings over the years and recent publications, this study compiles an updated checklist of bryophytes in Hebei Province. We analyzed the species composition, floristic characteristics, dynamic changes, and threatened status of bryophytes.
Results: The updated checklist documents 544 species across 190 genera and 76 families, including 468 mosses in 152 genera and 51 families, 75 liverworts in 37 genera and 24 families, and 1 hornwort. Among them, 8 families and 12 genera are dominant. The bryophyte flora of Hebei Province is predominantly characterized by northern temperate elements, with the proportion of temperate components outnumbering tropical ones. The checklist includes 33 species endemic to China, 4 Endangered species, and 5 Vulnerable species. Compared to the previous checklist, there are 10 newly recorded families, 34 newly recorded genera, and 162 newly recorded species, while 9 species have been removed and 86 names revised. The main newly reported groups include the families Mniaceae and Pottiaceae, and the genera Brachythecium and Bryum, etc.
Conclusions: The diversity of bryophytes in Hebei is relatively rich, though the investigation reveals regional imbalances. Future efforts should focus on strengthening bryophyte surveys in weak areas (e.g., Qinhuangdao, Tangshan, Handan), and timely updates to the checklist are necessary. In addition, under the background of global climate change, we should pay more attention to the dynamic changes in bryophyte populations to provide a scientific basis for the study and conservation of bryophyte diversity in Hebei Province.
