摘　　要：在野外实地调查,研究文献资料并系统整理出评价区维管束植物名录的基础上,对福建省北水南调第一期工程评价区的植物种类和区系成分进行分析。结果表明:工程评价区共有维管束植物1 153种,隶属于581属,186科。在植物区系地理成分科级分类阶层上,热带性质的地理成分居主导地位,占工程评价区维管束植物总科数的52.11%,尤以泛热带性质的地理成分居多;属级水平上,热带地理成分亦占优势,占维管束植物总属数的55.96%,温带地理成分也有较多分布。工程评价区具有维管束植物分布区类型较为齐全,热带成分居主导地位,温带成分居次,并具有一定特有成分等特点。Plant species and flora composition regarding the project of Fujian north-to-south water diversion were analyzed,based on field investigation,literature research and the list of vascular plants arrangement. The result showed that 1 153 species vascular plants（581 genera,186 families） were recorded in the evaluation zone. And,among the areal types of families,the tropical element was the dominant which accounted to 52. 11%,especially the pan tropical type was abundant. Among the area types of genera,the tropical element also occupied the dominant status which accounted to 55. 96%,with less temperate elements. This study indicated that geographical flora composition was complicated and closely associated with tropical flora,with a certain proportion of special ingredients.
