摘　　要：经野外采集和鉴定分析,贵州万山汞矿大水溪溪流生态系统苔藓植物由12科20属38种(含变种亚种)组成;其中,藓类含10科18属36种,苔类2科2属2种。丛藓科和真藓科为优势科,石灰藓属、真藓属、泽藓属为优势属。生活型含矮丛集型(44.74%)、高丛集型(36.84%)、交织型(13.16%)和平铺型(5.26%)4种类型。地理区系成分共7种,其中北温带分布、中国特有和热带亚洲为主要的地埋区系成分,具强烈的温热带性质,与该区地理位置和气候条件等相吻合,与种子植物的区系分布特点也一致。38 taxa in 22 genera of 12 families were found in Dashuixi stream ecosystem of Wanshan Mercury deposit,Guizhou province,P.R.China.Among them,36 taxa in 20 genera and 10 families are mosses while 2 species in 2 genera and 2 families are liverworts.Pottiaceae and Bryaceae were dominat families while Hydrogonium,Bryum and Philonotis are dominat genera.The life-forms are Short turfs（44.74%）,Wefts（13.16%）,Tall turfs（36.84%）,Mats（5.26%） and.There were 7 geographical elements of the flora such as Cosmopolitan,Tropical Asia,North Temperate,Temperate Asia,Eastern Asia,Pantropical elements and Endemic to China.Among of them,North Temperate,Endemic to China and Tropical Asia were dominat elements.The bryoflora obviously shows the temperate and tropical characters are similar to the flora of seed plants,locations and weather conditions.
