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.
