摘要
【目的】为进一步摸清云南轿子山国家级自然保护区内石松类和蕨类植物多样性、地理区系等特征,为该区域内石松类和蕨类植物利用和保护提供数据基础。【方法】基于云南轿子山国家级自然保护区的科学考察、日常监测数据以及文献资料收集等,从物种组成、地理区系等方面对轿子山保护区的蕨类植物物种多样性进行分析。【结果】云南轿子山国家级自然保护区共有蕨类植物120种,隶属15科31属。科占我国分布科的36.59%,其中包含5种以上科有鳞毛蕨科、凤尾蕨科、水龙骨科、蹄盖蕨科、冷蕨科5科。在属等级,耳蕨属Polystichum、鳞毛蕨属Dryopteris、铁线蕨属Adiantum具有最高的物种多样性,单种属有13个,占该地区全部属的41.94%,分布有云南省重点保护蕨类扇蕨1种;区系成分上,在科等级,世界广布科占据明显优势有12科;在属等级,世界广布属占据明显优势有12属;在种等级,东亚分布种占据明显优势有62种。
【Objective】To further explore and understand the biodiversity and geographical distribution patterns of lycophyte and fern flora in the Jiaozi Mountain National Nature Reserve of Yunnan,and to furnish data support for the conservation and utilization of these plants within the reserve.【Method】Drawing on data from scientific expeditions,routine monitoring efforts,and literature reviews conducted in the Jiaozi Mountain National Nature Reserve in Yunnan,this study analyzed the species diversity of fern flora in the reserve,focusing on species composition and geographical distribution.【Result】The results indicate that the Jiaozi Mountain National Nature Reserve harbors 120 lycophytes and ferns,which belong to 15 families and 31 genera,accounting for 36.59%of the total lycophyte and fern families in China.Among these,five families—Athyriaceae,Cystopteridaceae,Dryopteridaceae,Pteridaceae,and Polypodiaceae—each contain more than five species.At the genus level,Polystichum,Dryopteris,and Adiantum exhibit the highest species diversity,while monotypic genera account for 13(41.94%of the total genera).Additionally,one provincially protected species,Neocheiropteris palmatopedata was recorded.In flora,cosmopolitan families dominate at the family level(12 families);cosmopolitan genera prevail at the genus level(12 genera);and East Asian elements prevail at the species level(62 species).
