摘　　要：采集了桃红岭梅花鹿自然保护区苔藓植物标本600余份,共鉴定45科79属125种,其中苔纲14科16属21种,藓纲31科63属104种。优势科依次为:灰藓科、青藓科、丛藓科、提灯藓科、真藓科、羽藓科和曲尾藓科。单种科和单种属丰富,单种科21个,占总科数46.70%,单种属52个,占总属数65.80%。桃红岭苔藓植物的主要成分为东亚成分(34.40%)、北温带成分(24.00%)和热带亚洲成分(10.40%),体现热带亚洲向北温带转换的过渡性。与邻近15个地区苔藓植物区系构成进行比较分析,发现桃红岭与云居山关系密切,在中国苔藓植物地理分区中倾向归属于华中区。More than 600 bryophyte specimens were collected in TaohonglingSika Deer nature reserve. A to- tal of 125 species belonging to 45 families and 79 genera were identified. It was found that 21 species be- longing to 16 genera in 14 families were liverworts,while the rest of 104 species belonging to 63 genera in 31 families were mosses. Bryoflora of Taohongling was dominated by members of Hypnaceae,Brachytheci- aceae, Pottiaceae, Mniaceae, Bryaceae, Thuidiaceae, and Dicranaceae. Monotypic families and monotypic gen- era were very rich,including 21 families and 52 genera,accounting for 46.70% and 65. 80% of the whole families and genera respectively. Floristic analysis showed that East Asia,North temperate,and Tropica A- sia were the major elements,accounting for 34.40% ,24.00%, and 10.40% respectively, which indicated that the biogeographic region of Taohongling transited from Tropica Asia to North temperate. Compared with the distribution of 15 adjacent areas, Taohongling showed close relationships with Yunju Shan,and they together tended to belong to Central China region within all bryological regions of China.
