摘　　要：目的:掌握羊狮慕石松类和蕨类植物资源多样性。方法:通过野外线路调查、采集标本及鉴定等方法,分析羊狮慕石松类和蕨类植物的物种组成及区系成分,并与江西5个保护区进行相似性比较。结果:羊狮慕共有石松类和蕨类植物23科66属167种(含变种、亚种和变型),其中石松类植物2科4属14种,蕨类植物21科62属153种。羊狮慕石松类和蕨类植物区系成分复杂,区系成分以中国-日本分布最高;温带成分高于热带成分,表现出较明显的温带性质,并呈现出热带性质向温带性质过渡现象。羊狮慕与江西5个保护区属的相似性都较高;种的水平上与井冈山相似性最高,与赣南九连山、齐云山和赣北庐山相似性基本一致。结论:羊狮慕石松类和蕨类植物资源丰富,是江西赣南与赣北物种交汇地带之一。本研究为江西石松类和蕨类植物研究提供基础数据。Objective:To investigate the diversity and resources of lycophytes and ferns in Yangshimu.Methods:The species and floristic composition of lycophytes and ferns were analyzed by field investigation,specimen collection and identification.Comparisons were then made with five protected areas in Jiangxi Province.Results:The Yangshimu area hosted 23 families,66 genera,and 167 species(including variants,subspecies,and forma)of lycophytes and ferns.Specifically,there were 2 families,4 genera,and 14 species of lycophytes,and 21 families,62 genera,and 153 species of ferns.The floristic composition was complex,with the majority belonging to the Sino-Japan(SJ)region.The number of temperate species exceeded that of tropical comparable,indicating a clear temperate nature with temperate to tropical transition.The similarities between Yangshimu and 5 protected areas in Jiangxi were equally high at the genus level.Yangshimu showed the highest similarity to Jinggang Mountain at the species level,while its similarities to Jiulian Mountain,Qiyun Mountain(both in southern Jiangxi)and Lu Mountain(in northern Jiangxi)were generally comparable.Conclusion:Yangshimu was rich in lycophytes and ferns resources,suggesting that this area was a juncture of southern and northern Jiangxi.This study provided basic data for future research on lycophytes and ferns in Jiangxi.
