摘要
在对莆田至永定高速公路评价区野外实地调查并结合文献研究资料,系统整理出评价区维管束植物名录的基础上,对该区域的植物种类组成和区系成分进行分析.结果表明:评价区共有维管束植物1 914种,隶属于831属,213科,植物物种多样性较为丰富.在植物区系地理成分中,科级水平上,热带性质的成分居主导地位,占总科数的62.5%,尤以泛热带成分分布居多,世界分布次之,占总科数的48.7%,温带分布亦较丰富,占总科数的17.1%.属级水平上,热带成分亦占优势,占总属数的60.7%,温带分布多于世界分布,分别占总属数的12.3%、11.8%.评价区具有区系地理成分复杂多样,与热带植物区系关系密切,特有性成分占有一定比例等特点.
We analyzed the plants species and flora composition from the highway evaluation zone Putian to Yongding,based on the ways of field investigation,literature research and the list of vascular plants arrangement.Our result showed that： 1 914 species vascular plants（ 831 genera,213 families） were recorded in the evaluation zone.It was abundant with plants species and diversity.Among the areal types of families,the Tropical element was the dominant which accounted to 62.5%,especially the Pantropic was abundant,and the Cosmopolitan（ 48.7%） was less.The Temperate elements were abundant with the percent of 17.1%.Among the areal types of genera,the Tropical element also occupied the dominant status which accounted to 60.7%,but the Temperate elements（ 12.3%） outnumbered the Cosmopolitan（ 11.8%）.The study indicated that geographical flora composition was complicated and closely associated with tropical flora,and the special ingredients occupied certain proportion,etc.
