摘要:

物种编目是区系研究、生物多样性监测和珍稀濒危生物保护的基础。宁夏维管植物编目对该区植物多样性保护和资源植物开发利用具有重要意义。本文在《宁夏植物志(第二版)》的基础上, 结合多年野外实地调查数据和相关文献资料, 按照APG Ⅳ分类系统修订了宁夏野生维管植物名录。结果显示: 宁夏有野生维管植物127科597属1,754种, 排名前10的优势科分别是菊科、禾本科、豆科、蔷薇科、毛茛科、苋科、唇形科、莎草科、石竹科和伞形科, 这10科共有物种939种, 占宁夏野生维管植物总数的53.53%; 科的组成以物种数小于20种的科为主, 属主要以小于5种的属为主; 2007年至今累计发现新记录植物230种; 宁夏有珍稀濒危植物25科44属65种; 外来归化、逸生及入侵植物9科22属28种。就国土面积和地理位置而言, 宁夏野生维管植物较为丰富。本研究结果可为《宁夏植物志(第三版)》修订和生物多样性监测与保护提供基础数据。

Abstract

Aims: Species cataloguing is the basis for studies of flora, monitoring of biodiversity, and the conservation of rare and endangered species. The vascular plant catalogue of Ningxia is of great significance for the protection of plant diversity, and the development and utilization of plants.
Method: Based on Ningxia Flora (2nd edn), this article combined the data from years of field work and published literature to revise the lists of wild vascular plants in Ningxia according to APG IV classification system.
Results: There are 1,754 species of wild vascular plants belonging to 597 genera and 127 families. The top 10 dominant families were Asteraceae, Poaceae, Fabaceae, Rosaceae, Ranunculaceae, Amaranthaceae, Lamiaceae, Cyperaceae, Caryophyllaceae, and Apiaceae, which are comprised of 939 species, accounting for 53.53% of the total. The family composition is dominated by those with less than 20 species, and the genus composition is dominated by those with less than 5 species. A total of 230 newly recorded species have been found in Ningxia since 2007. There are 65 species of rare, endangered plants belonging to 44 genera and 25 families, and 28 species of invasive plants belonging to 22 genera and 9 families.
Conclusion: In terms of land areas and location, the diversity of wild vascular plants in Ningxia is abundant. The results can provide basic data for the revision of Ningxia Flora (3rd edn) and the monitoring and conservation of biodiversity.
