摘　　要：目的:了解福建野生水生植物资源物种组成、地理成分及保护利用情况。方法:采用野外调查和文献资料整理的方法对福建地区的野生水生植物资源进行调查和区系分析。结果:福建有野生水生植物589种,隶属119科305属;蕨类植物22科35属48种,裸子植物1种,被子植物96科269属540种;其中国家一级保护野生植物2种,二级保护野生植物15种,中国特有植物13种;该区科级地理成分有7个分布区型和6个变型,R/T值为2.19,表现出典型的热带区系性质,属级地理成分13个分布区型和11个变型,R/T值为1.17,表明福建野生水生植物地理成分复杂,具有亚热带过度的区系特征。结论:福建野生水生植物资源丰富,有多种珍稀植物,应重点保护并合理开发。Objective:To investigate the species composition,geographical distribution,protection and utilization of wild aquatic plant resources in Fujian.Methods:Field investigations and literature reviews were conducted to analyze the wild aquatic plant resources in the Fujian region.Results:A total of 589 species of wild aquatic plants were identified in Fujian,belonging to 305 genera and 119 families.The study identified a total of 48 species of ferns(belonging to 35 genera and 22 families),1 species of gymnosperms,and 540 species of angiosperms(belonging to 269 genera and 96 families).Among these,2 species were designated as national first-class protected wild plants,15 species as second-class protected wild plants,and 13 species were found to be endemic to China.At the family level,7 distribution types and 6 variants were observed,with an R/T value of 2.19,indicating a typical tropical flora.At the genus level,13 distribution types and 11 variants were identified,with an R/T value of 1.17,reflecting the complexity and subtropical transitional characteristics of the geographical elements of wild aquatic plants in Fujian.Conclusion:Fujian was rich in wild aquatic plant resources,including a significant number of rare species.These plants should be given priority for protection and developed in a rational manner.
