摘要: 对福建植物生物多样性从物种多样性、遗传多样性和生态系统多样性三个层面进行了评价,分析了植物生物多样性的特点.在此基础上提出了影响福建植物生物多样性的主要生物安全问题.研究表明,福建植物生物多样性具有植物种类丰富,热带和亚热带的科属种类多、起源古老,中国特有成分比例较高和国家重点保护植物较为丰富等特点.影响植物生物多样性的主要生物安全问题包括阔叶林面积不断减少,森林资源总体质量下降;濒危野生植物比重增大,名木古树破坏严重;外来物种入侵呈加重趋势.

Abstract: Plant biodiversity was assessed for Fujian Province from three aspects:species diversity,genetic diversity, and ecosystem diversity.The primary bio-safety influencing factors were suggested for plant biodiversity in Fujian Province.The plant biodiversity in Fujian was abundant.Many species were from tropical and sub-topical families and genus,with ancient origionation.There were also many native Chinese species which are on the list of nationally protected important species.The main problems influencing bio-safety included the continuous shrink of broad-leaved forest,the decrease of general quality of forest resources,the increase of the proportion of endangered wild plants, the heavily destroyed ancient trees, and deteriorated exotic species invation.
