摘　　要：对黔西南红土型金矿苔藓植物的调查结果显示,黔西南红土型金矿苔藓植物共14科53属124种,其中苔类植物1科2属2种分别为叶苔科叶苔属拟卵叶叶苔和细茎叶苔;藓类植物13科52属122种。与云南东川拖布卡-播卡金矿苔藓植物比较发现,黔西南红土型金矿苔藓植物丰富度大于云南东川拖布卡-播卡金矿,生活型以丛集型为主,两矿区共有科为3科,共有属为10属,相同种为10种,种的相似性较小,种的相似性系数为6.99%,属的相似性指数为15.87%,科的相似性指数为17.6%,其相同种中土生对齿藓Didymodon vinealis(Brid.)Zander、云南墙藓Tortula yunnanensis P.C.Chen和硬叶小金发藓Pogonatum neesii(C.Muell.)Dozy.分布较广泛,可进一步作为生态修复研究的材料。Based on the comprehensive investigation, collection, identification of the bryophyte specimens, 124 mosses species in 53 genera of 14 families were found at lateritic gold deposits in SW Guizhou. Liverworts 1 family in which 2 genera and 2 species were leaf leaves moss families are to be eggs and fine leaf moss stems and leaves; mosses, 122 species of 13 families and 52 genera. Through the statistic of the toubuka-Boka gold mine in Dongchuan discover bryophytes comparison, turfs is the dominant life-forms of bryophytes. Lateritic gold deposits in southwest Guizhou bryophyte lichness is higher than Tuobuka-Boka gold mine of Yunnan.There are mosses for 3 families, 10 genera and 10 species are common, in the two fields, species similarity coefficient of 6.99%, genera is 15.87%, families 17.6% similarity index, Didymodon vinealis （Brid.） Zander, Tortula yannanensis P.C.Chen and Pogonatum neesii （C.Muell.） Dozy. distributed widely in the two gold mines, they may be used to a good material for ecological restoration in the future.
