摘　　要：【目的】探讨汀江源自然保护区石松类和蕨类植物从物种多样性和区系地理特征,以期为两类植物多样性保护、资源应用开发及系统演化等研究提供参考。【方法】在野外调查、标本鉴定基础上,结合文献资料,整理该区石松类和蕨类植物名录,分析区系组成及地理成分。【结果】(1)该区石松类和蕨类植物有23科60属129种,其中石松类有2科5属15种,蕨类植物有21科55属114种。(2)优势科、属明显,优势科有3科,优势属有1属;单种科、属和寡种科、属是构成该区石松类和蕨类植物科、属的主体。(3)科的分布区类型以世界分布和热带分布为主;属、种的分布区类型以热带分布为主,同时呈现温带性质;中国特有种有15种。(4)该区与梁野山保护区的地理亲缘关系最近。【结论】汀江源国家级自然保护区石松类和蕨类植物地理成分多样,特有现象明显,生物多样性较低,植物区系成分在水平梯度上呈现由热带向温带过渡的特征。[Objective]The objective of this study is to investigate species diversity and floristic geograph-ical characteristics,in order to provide a reference for the research on the diversity conservation,resource application and development,and phylogenetic evolution of lycophytes and fern in the Tingjiangyuan Na-ture Reserve.[Methods]On the basis of field investigation and specimen identification,combined with the literature data,the list of lycophytes and fern in the area was compiled,and the faunal composition and ge-ographical composition were analyzed.[Results](1)There were 129 species of lycophytes and ferns in 60 genera and 23 families,including 15 species of lycophytes in 5 genera and 2 families,and 114 species of ferns in 55 genera and 21 families.(2)The dominant families and genera were obvious,with 3 families and 1 genus of the dominant families.Monospecific families,genera,and oligogenes were the main bodies of the lycophytes and fern families and genera in the area.(3)The distribution types of families were mainly global and tropical,and the distribution types of genera and species were mainly tropical and tem-perate.There were 15 endemic species in China.(4)The geographical kinship between this area and the Liangye Mountain Nature Reserve was the closest.[Conclusion]The geographical composition of the lyco-phytes and fern plants in the Tingjiangyuan National Nature Reserve is diverse,with obvious endemic phenomena and low biodiversity.The plant flora shows a transition from tropical to temperate on a horizontal gradient.
