| 摘 要： | 为探明梵净山自然保护区蕨类植物(含石松类植物,下同)的区系特点,结合野外调查、标本鉴定及资料整理的方法,调查了梵净山蕨类植物种类,并分析了梵净山蕨类植物属与种的各种区系成分。主要结果有:1)梵净山自然保护区共有蕨类植物28科,87属,324种,7变种和3变型。2)属的区系分析表明本区蕨类植物区系在属一级上带有明显的热带性质,但温带成分对本区区系也有一定影响。3)种的区系分析显示本区蕨类植物区系在种一级上具有温带性质,处于东亚蕨类植物区系的东翼及我国蕨类植物区系的中心区域,热带亚洲成分向北扩散也对本区蕨类植物的区系特征造成影响。

| Abstract: | To explore the characteristics of pteridophytes flora in Mt.Fanjingshan Nature Reserve,we investigate the diversity of pteridophytes species by field works,specimen identification and reference collating,and analyze areal-types of genera and species of pteridophytes in this area.Major results are as follow：1） There are totally 28 families,87 genera,324 species,7 varietas and 3 forma of pteridophytes in Mt.Fanjingshan Nature Reserve.2）Analysis of pteridophytes flora on genera shows that pteridophytes flora on genera level have obvious tropical character,but temperate genera also influence the characteristics of genera flora to some degree.3） Analysis of pteridophytes flora on species shows that pteridophytes flora on species level have temperate character in Fanjingshan Nature Reserve,pteridophytes flora in this area are located in the east wing of east Asia pteridophytes flora and central area of China pteridophytes flora.Tropical Asia species have some influence to the characteristics of species flora via spreading to northern regions. |
