| 通过对采集的759份苔藓植物标本进行鉴定，首次报道了花鸟山岛苔藓植物种类组成，区系地理成分及特点.研究结果表明：1）花鸟山岛共有苔藓植物103种，其中苔类植物8种，隶属于4科5属，藓类植物95种，隶属于22科41属；2）花鸟山岛中丛藓科（Pottiaceae）为第一大科，有9属18种；真藓属（Bryum）为第一大属，有10种；3）花鸟山岛中苔藓植物区系成分是以东亚成分为主（占总种数的36.96%），温带成分次之（占总种数的35.87%），热带成分再次之（占总种数的20.65%）；4）花鸟山岛苔藓植物生态分布类型复杂多样，以土生类型（占总标本数的61.92%）最多，石面薄土（占总标本数的12.87%）和砂土生（占总标本数的7.77%）、石土生（占总标本数的7.25%）、石生（占总标本数的7.11%）次之，树生（占总标本数的1.84%）和墙面薄土生（占总标本数的1.32%）再次之. |

| Abstract: |
| Based on identification of collections of 759 bryophyte samples,bryological composition and floristic characteristics in Huaniaoshan Island were analyzed. The results showed that:1) A total of 103 bryophyte species in Huaniaoshan Island were reported,including liverworts 8 species belonging to 4 families and 5 genera,and 95 species of mosses belonging to 22 families,41 genera. 2) Pottiaceae is the largest family with 9 genera and 18 species;Bryum is the largest genus containing 10 species in Hua'niaoshan Island;3) The floristic types of bryophytes in Huaniaoshan Island showed that East Asia element was dominant (accounted for 36.96% of the total species);Temperate element followed (accounted for 35.87% of the total species);Tropical element was the third one (accounted for 20.65% of the total species);4) The ecological distribution types of bryophytes were complicated in Huaniaoshan Island. The most common type was on soils (61.92% of the total samples),thin soil on rocks (12.87% of the total samples) was the second,soil on sands (7.77% of the total samples) was the third,and soil on rocks (7.25% of the total samples) was the fourth,on rocks (7.11% of the total of samples) was the fifth,on trees (1.84% of the total of samples) was the sixth,thin soils on wall (1.32% of the total samples) was the last. |
