| 摘 要： | 通过野外调查和查阅文献资料，分析了纳雍珙桐自然保护区蕨类植物的种类组成和区系特征。结果表明：（1）纳雍珙桐自然保护区共有蕨类植物30科61属134种（含种下分类单位），其中以鳞毛蕨科、水龙骨科、蹄盖蕨科等为主；（2）蕨类植物区系成分复杂，区内温带种占绝对优势，为总种数的89．7％，具温带性质。其中，东亚分布有108种，占总种数的80．6％，说明为东亚区系。热带分布种8种，世界广布种5种，说明区内蕨类植物与热带有一定的联系，并且有较广泛的地理联系性；（3）与贵州大部分地区处在植物分布区的过渡地段上一样，比较多的属（52．5％）在这里只有1种分布，具有其过渡性质：（4）贵州省纳雍国有林场地区蕨类植物在科属上具有一定的丰富性同时具有一定的特殊性。

| Abstract: | The floristic composition and geographic feature of pteridophyte in Nayong Dove Tree Nuture Reserve were analyzed based on field investigation and data collection. A total of 30 families, 61genera and 134 species （containing the taxa below the species） of pteridophyte were obtained, most of which were Dryopteridaceae, Polypodiaceae or Aspleniaceae. The type of pteridoflora was complicated, and the pteridophyte showed obviously temperate property, accounting for 89.7 % of the total species, among which, 108 belonged to the East - Asia species, accounting for 80. 6 % of the total. Additionally, there were 8 tropical species distribution and 5 cosmopolitans species, indicating that pteridophyte in this area had widely geographic relation. As the most areas in Guizhou Province, Nayong Dove Tree Nuture Reserve located in transition section, and most of genera （52.5 % ） contained only one species. The pteridophyte in Nayong Dove Tree Nuture Reserve was considerably rich in families and genera, as well as showed fairly particularity. |
