| 摘要: |
| 漓江流域地处广西东北部,喀斯特地区发育有最为典型的峰林平原和峰丛洼地地貌,是广西喀斯特地貌分布最为典型和集中的区域之一,其古老的地质构造孕育了独特的喀斯特景观和复杂的生态系统,为物种的汇聚创造了有利条件,使之成为生物多样性丰富区域。为全面掌握漓江流域喀斯特地区植物多样性本底情况,通过文献查阅、野外调查和标本鉴定,对该区域的植物多样性进行了研究,重点分析了物种多样性组成、区系地理成分、特有植物和重点保护植物等。结果表明:(1)目前该区共记录有野生维管植物1 273种,其中石松类和蕨类植物97种,裸子植物5种,被子植物1 171种; 植物区系成分以热带成分为主。(2)该区分布有中国特有属16属,广西特有植物55种,喀斯特专性植物124种; 还分布有国家重点保护野生植物18种,广西重点保护野生植物18种。该研究结果对漓江流域喀斯特地区植物资源本底情况有了较为全面的掌握,可为漓江流域生态保护和桂林国家可持续发展议程创新示范区建设提供科技支撑。 |

| 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 provides 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. |
