摘要
为黄荆自然保护区蕨类植物资源保护提供依据,采用实地踏查法研究黄荆自然保护区蕨类植物的区系特征。结果表明:保护区有蕨类植物37科68属163种,蕨类植物区系成分复杂,类型丰富;优势科属明显,科内及属内分化程度较高,种类组成丰富;科的地理成分以热带成分占优势,属的地理成分以温带成分为主;生境特点以土生为主;与贵州赤水桫椤和四川江津四面山保护区的属种相似性系数最高,关系最为密切。
Pteridophyte flora from Huangjing Nature Reserve was studied by field survey method to provide a basis for fern resources protection.Results：The floristic components of Huangjing Nature Reserve are complex and the taxa are abundant,including 37 families,68genera,and 163 species of ferns.The dominant families and genera are obvious;Their intra-family and intra-genus differentiation are high and their species composition are diverse.The tropical elements predominate at the level of family.However,temperate elements predominate at the level of genus.Their habitats are terrestrial.The genusspecies similarity coefficient of Huangjing Reserve is the most closely related to those of Suoluo Reserve in Chishui Guizhou and Simianshan Reserve in Jianqjin Sichuan.
