摘要:

拟建西南岩溶国家公园(广西片区)具有原生性强的亚热带岩溶森林生态系统和岩溶洞穴生态系统,孕育了丰富多样的野生植物资源。为了探明拟建西南岩溶国家公园(广西片区)的植物多样性本底,为西南岩溶国家公园的创建提供重要的参考资料,该文通过多年野外调查、资料查阅整理及标本鉴定,最终确定了广西岩溶地区分布的4个广西新记录属和25个广西新记录植物。在这25种新记录植物中,包括了多数的岩溶特有植物,具有明显的岩溶适应性,这些适应性使得这些植物在水土保持、石漠化治理、生态系统修复等方面具有潜在利用价值。此外,这些新记录物种具有一定开发利用价值,如药用、园林绿化及培育新品种等。本次发现的新记录属和新记录种均位于拟建西南岩溶国家公园的广西片区内,它们的发现不仅是广西岩溶地区物种多样性的一个重要表现,而且还为西南岩溶国家公园的资源本底状况增添了新资料,同时对进一步开展植物保护研究和开发利用具有重要的参考价值,使广西岩溶地区的保护工作科学有效进行。此外,文中提供了各新记录物种的主要形态特征描述、标本引证、彩色照片及地理分布等。

Abstract:

The proposed Southwest Karst National Park(Guangxi area), has a strong original subtropical karst forest ecosystem and karst cave ecosystem, and breeding rich and diverse wildlife plant resources. In order to explore the background data on plant diversity and provide important information for the proposed Southwest Karst National Park(Guangxi area), years of fieldwork, literature materials collection and specimen identification in this paper, and subsequently, four new record genera and 25 species of plants are found from this areas. Among this 25 new recorded plants, most of them are karst endemic and have obvious karst adaptability, which makes these plants have potential utilization value in soil and water conservation, rock desertification control, and ecosystem restoration. In addition, they have certain development and utilization value, such as can be used for medicine, landscaping, and breeding new varieties. The discovery of these species is not only an important manifestation of the plant diversity in the karst areas of Guangxi, but also adds new information for the plant resource of the proposed Southwest Karst National Park. And moreover it has important reference value for further plants protection research and development and utilization, which makes protection work of karst areas in Guangxi scientifically and effectively. The paper also provides descriptions of various main morphological characteristics, specimen citations, color photos and geographical distribution.
