漓江流域喀斯特地区植物多样性研究
Research on plant diversity in the karst area of the Lijiang River basin
摘要
Abstract
The Lijiang River basin is located in Northeast Guangxi,China.The karst area here features the most typical peak forest plains and peak cluster depressions,making it one of the regions with the most typical and concentrated karst landform in Guangxi.Its unique karst landscapes and complex ecosystems,creating favorable conditions for the convergence of species and making it a region rich in biodiversity.To comprehensively understand the plant diversity in the karst area of the Lijiang River basin,a study was conducted through literature review,field investigation,and specimen identification,focusing on the composition of species diversity,floristic geographical components,endemic plants,and key protected plants etc.The results are as follows:(1)There are currently 1 273 species of wild vascular plants recorded in this area,including 97 species of lycophytes and ferns,5 species of gymnosperms,and 1 171 species of angiosperms;the floristic composition is dominated by tropical components.(2)There are 16 Chinese endemic genera,55 endemic species of Guangxi,and 124 karst obligate plants recorded in this area;additionally,there are 18 wild plant species under national key protected and 18 wild plant species under Guangxi key protection found from this area.The results of this research provide a comprehensive understanding of plant resources in the karst area of the Lijiang River basin,which can offer science and technology support for the ecological protection of the Lijiang River and the construction of the Guilin National Sustainable Development Agenda Innovation Demonstration Zone.关键词
