| 广西维管植物物种数量随着野外调查与研究的深入而不断增加,也更具多样性。近25年来,关于广西维管植物新分类群(新种、新变种、新亚种和新变型等)的资料分散在各种出版物中,有必要及时整理和统计,从而全面展示其种类组成、物种分布、类群特色以及保护现状等,为广西植物多样性保护与持续利用提供重要资源保障。该文通过广泛的文献整理和数据校正,统计结果表明:(1)2000—2024年间报道的广西维管植物新分类群共683个,隶属于85科206属,科以苦苣苔科(Gesneriaceae)、秋海棠科(Begoniaceae)、天门冬科(Asparagaceae)、荨麻科(Urticaceae)为主; 属以报春苣苔属(Primulina)、秋海棠属(Begonia)、蜘蛛抱蛋属(Aspidistra)和楼梯草属(Elatostema)的种类占优势。(2)新分类群具有极高的珍稀特有性,其中属于石灰岩专性植物占总种数的70.42%,广西特有种占总种数的85.51%,受威胁植物种数占总种数的49.93%, 国家重点保护植物22种,广西重点保护植物24种。(3)生物多样性丰富的喀斯特地区是植物新分类群的主要发现地,非保护区比保护区报道更多的植物新类群,靖西市是报道广西新分类群最多的县级区域。(4)科研院所是广西新分类群的主要贡献机构,其中以广西植物研究所为主导。这些植物新分类群的发现和报道展示了广西丰富的植物多样性,是广西生态环境质量提升的重要体现。 |

| Abstract: |
| The species number of vascular plants in Guangxi is increasing and the diversity is more rich with the deepening of field investigation and research. In the last 25 years, data about new taxa of vascular plants in Guangxi(new species, new varieties, new subspecies and new variants, etc.)have been scattered in various publications. It is necessary to collate and make statistics in time. Thus, the species composition, distribution, distinctive taxa and conservation status can be fully displayed, and provided an important resource guarantee for the protection and sustainable utilization of plant diversity in Guangxi. Based on extensive literature review and data proofreading, the statistical results are as follows:(1)A total of 683 new taxa of vascular plants belonging to 85 families and 206 genera in Guangxi have been reported from 2000 to 2024. The dominant families and genera were Gesneriaceae, Begoniaceae, Asparagaceae, Urticaceae, Primulina, Begonia, Aspidistra and Elatostema.(2)The new taxa are highly rare and endemic, including 70.42% of limestone specific, 85.51% of Guangxi endemic, 49.93% of threatened, 22 species under state key protected protection, and 24 species under Guangxi key protected protection.(3)Karst areas rich in biodiversity are the main distribution, and more new taxa are reported in non-protected areas than in protected areas. Jingxi City is the county-level region where the most new taxa have been reported.(4)The research institutes are the main contributors to the new taxa in Guangxi, and led by Guangxi Institute of Botany. The discovery and report of these new plant taxa are the important embodiment of the rich plant diversity and the improvement of ecological environment quality in Guangxi. |
