摘　　要：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.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,ontrees( 1. 84% of the total of samples) was the sixth,thin soils on wall( 1. 32% of the total samples) was the last.
