摘　　要：为补充浙江景宁九龙地质公园蕨类植物多样性研究的空白,进一步提高对该地区蕨类植物多样性的了解,夯实保护和管理基础,笔者通过踏查法对该地区的蕨类植物展开调查。结果表明:(1)景宁九龙地质公园共有30科58属120种蕨类植物,其中九龙片区有25科48属91种,炉西峡片区有27科48属85种。(2)景宁九龙地质公园优势科为鳞毛蕨科Dryopteridaceae、水龙骨科Polypodiaceae和蹄盖蕨科Athyriaceae,其中九龙片区优势科为鳞毛蕨科和水龙骨科,炉西峡片区优势科为鳞毛蕨科。(3)景宁九龙地质公园区系分析表明,科的分布区类型有6种类型,属的分布区类型有9种类型,种的分布区类型9种。在世界植物区系联系上,地质公园与东亚地区、印度-马来区联系最为密切。九龙地质公园生境复杂,蕨类植物种类丰富,保育有福建观音座莲、金毛狗等众多珍稀植物;植物区系起源复杂,科、属分布区类型具较明显热带特征,种的分布类型具较明显的温带特征,总体呈现热带起源向温带过渡特征。在种级水平上,2个片区联系紧密又各有特色,南部炉西峡片区热带成分高于九龙片区,与地理位置相吻合,是温度、地貌、光照等多种生态因子综合作用的影响。综上,建议在公园内建立小型生态观测站,深入分析各生态因子对蕨类植物分布的影响,为后续的管理和保育工作提供科学依据。In order to fill the gap in research on the diversity of ferns in the Jingning Jiulong Geological Park in Zhejiang Province,further improve our understanding of the diversity of ferns in the area,and strengthen the foundation of protection and management.The author conducted a survey on the ferns in the Jingning Jiulong Geological Park area through the method of investigation.The studies showed that:(1)Jingning Jiulong Geopark hosted a total of 30 families,58 genera,and 120 species.Specifically,the Gorgepark encompassed 91 species within 25 families and 48 genera,whereas the Luxi Gorge area had 85 species distributed among 27 families and 48 genera.(2)The predominant families in Jingning Jiulong Geological Park included Dryopteridaceae,Polypodiaceae,and Athyriaceae.Notably,Dryopteridaceae and Polypodiaceae were predominant families in the Jiulong Gorge area,whereas Dryopteridaceae stood out in the Luxi Gorge area.(3)The fern flora composition analysis of Jingning Jiulong Geological Park showed that there were six distribution types at the family level,nine at the genus level,and nine at the species level.In terms of global plant distribution,this geological park was closely connected to the East Asian and the Indo-Malay region.The park had a complex habitat,with a rich variety of fern species,and it conserved many rare plants such as Angiopteris fokiensis and Cibotiu barometz.The origin of the ferns flora was complex.The distribution area of families and genera both exhibited distinct tropical characteristics,while the species-level distribution showed evident temperate features,overall representing a transition from a tropical origin to temperate conditions.At the species level,the two regions were closely connected yet each had its own distinct characteristics.The southern Luxi Gorge area exhibited a higher tropical component compared to the Jiulong Gorge area,aligned with geographical location.It was influenced by the combined effects of multiple ecological factors such as temperature,topography,and light.In c
