摘要:

为全面了解青海野生维管植物资源现状, 为青海植物多样性保护提供本底资料, 本文在已有历史资料的基础上, 全面收集青海植物研究的相关文献, 结合多年野外调查数据和标本信息, 整理并更新了青海野生维管植物名录, 85.01%的物种和种下类型附有凭证标本(包括采集人、标本采集号和条码号)、产地、生境、分布等信息。青海共分布野生维管植物109科602属2,916种(含亚种、变种), 其中, 石松类和蕨类植物12科20属55种; 裸子植物3科6属36种; 被子植物94科576属2,825种, 与《青海植物名录》相比增加了500种。统计结果显示, 青海省野生维管植物中物种数排名前10位的优势科分别为菊科(346种)、禾本科(343种)、豆科(222种)、毛茛科(160种)、蔷薇科(146种)、十字花科(113种)、列当科(96种)、龙胆科(90种)、莎草科(86种)和石竹科(84种), 总计1,686种, 占青海野生维管植物总数的57.82%; 排名前5位的优势属分别为黄芪属(Astragalus, 95种)、马先蒿属(Pedicularis, 83种)、风毛菊属(Saussurea, 76种)、蒿属(Artemisia, 66种)和薹草属(Carex, 65种); 科的组成以小于20种的科为主, 属的组成以小于5种的属为主。同时, 本名录共收录国家重点保护野生植物47种(均为二级), 分属17科25属。本名录将为青海植物本底资源调查、野外监测、种质资源收集保存、生物多样性保护等提供可靠的理论依据。

Abstract

Aim: In order to comprehensively understand the current status of wild vascular plant resources and to provide the basic information for the conservation of plant diversity, it is necessary to compile, improve and update the checklist of Qinghai plants.

Method: Based on the existing historical data, we comprehensively collected relevant literature on plant research in Qinghai Province, combined data from years of field surveys and specimen information, and compiled a checklist of wild vascular plants. 85.01% of the species are accompanied by voucher specimens (including collector, specimen collection number, and barcode number), provenance, habitat, and distribution information of each species and infraspecies.

Results: There were 2,916 species (including subspecies) of wild vascular plants in 109 families and 602 genera in Qinghai Province, including 55 species from 12 families and 20 genera of lycophytes and ferns; 36 species from 3 families and 6 genera of gymnosperms; 2,825 species from 94 families and 576 genera of angiosperms, with 500 species added compared with the Index Florae Qinghaiensis. The results showed that the top 10 dominant families of wild vascular plants in Qinghai Province were Asteraceae (346 species), Poaceae (343 species), Fabaceae (222 species), Ranunculaceae (160 species), Rosaceae (146 species), Brassicaceae (113 species), Orobanchaceae (96 species), Gentianaceae (90 species), Cyperaceae (86 species), and Caryophyllaceae (84 species), which were comprised of 1,686 species, accounting for 57.82% of the wild vascular plants in Qinghai Province. The top 5 dominant genera were Astragalus (95 species), Pedicularis (83 species), Saussurea (76 species), Artemisia (66 species), and Carex (65 species). The composition of families is dominated by families with less than 20 species, and the composition of genera is dominated by genera with less than 5 species. Meanwhile, the checklist contained a total of 47 species of national key protected wild plants, belonging to 17 families and 25 genera, all of which were under the second level of protection.

Conclusion: The checklist can provide basic data for field survey and monitoring, collection and preservation of germplasm resources and biodiversity conservation.
