龙滩自然保护区植物生物多样性特点及其生态安全问题

摘要

从物种多样性、遗传多样性、生态系统多样性3个层面对龙滩自然保护区植物生物多样性进行了评价,分析了龙滩自然保护区植物生物多样性的特点,并提出了影响植物生物多样性的主要生态安全问题.结果表明,龙滩自然保护区植物种类丰富,有维管植物205科、1 029属、2 821种;影响植物生物多样性的主要生态安全问题为珍稀濒危野生植物破坏及外来物种的入侵.%The characteristic and status of plant biodiversity in Longtan Nature Reserve was evaluated from the three aspects of biodiversity, species diversity, genetic diversity and ecosystem diversity. And the primary eco-safety influencing factors for plant biodiversity in Longtan Nature Reserve were put forward. The results show that the plant biodiversity in Longtan Nature Reserve was abundant, there were 2821 species of vascular bundle plants belonging to 1029 genera, 205 families. The main problems influencing eco-safety included the destruction of endangered wild plants and exotic species invation.
