| 摘要: |
| 植物模式标本是发表新分类群名称时所依据的特殊实物标本，作为极其珍贵的学术资料，其在植物分类学研究中有着不可替代的重要价值。为深入了解以贵州为模式标本产地的石松类和蕨类植物现状，本研究对现有馆藏的贵州石松类和蕨类植物模式标本及国内外原始文献进行收集、整理及系统分析，采用蕨类植物系统发育研究组第一版(Pteridophyte Phylogeny Group Ⅰ，PPG Ⅰ)分类系统对模式标本物种构成进行系统梳理，并探讨其地理分布格局。结果表明，以贵州为模式标本产地的石松类和蕨类植物共23科54属221种，系统厘清被处理为异名(Synonym)的模式标本物种共17科37属103种。地理分布格局分析结果表明该类群模式标本呈现显著的聚集性分布特征，在黔中、黔南地区形成明显分布热点。本研究成果可为贵州石松类和蕨类植物的分类学研究与资源保护利用提供重要科学依据。 |

| Abstract: |
| Plant type specimens are special physical specimens on which new taxon names are based,and they are extremely valuable academic materials with irreplaceable importance in taxonomic research.To deeply understand the current status of type specimens of lycophytes and ferns in Guizhou,this study systematically collected,collated,and analyzed the type specimens preserved in herbaria,as well as domestic and international literature.Subsequently,the Pteridophyte Phylogeny Group Ⅰ(PPG Ⅰ) classification system was employed to systematically clarify the taxonomic composition of these type specimens and explore their geographical distribution pattern.The results revealed that a total of 221 species of lycophytes and ferns,belonging to 54 genera of 23 families,had Guizhou as their type locality.Furthermore,103 species belonging to 37 genera of 17 families that were previously treated as synonyms were systematically clarified.The spatial distribution analysis demonstrated a significant aggregation pattern,with distinct distributional hotspots identified in central and southern Guizhou.These findings offer important scientific insights for the taxonomic research,conservation,and sustainable utilization of lycophytes and ferns in Guizhou. |
