摘 要 ：经野外采样及鉴定，发现在云南东川汤丹铜矿分布着6科（丛藓科、真藓科、青藓科、羽藓科、牛毛藓科和绢藓科）16属（扭口藓属、净口藓属、对齿藓属等等）22种苔藓植物，其中59%是丛藓科植物，为优势科。并且这些苔藓植物中有62%是直接生活在布满铜绿的矿岩石上，另外38%是生活在含氧化铜的矿土上。苔藓植物生活型有三种：矮丛集型占68%、高丛集型14%、交织型18%。区系分布类型有7种（东亚和北美分布、中国特有分布、热带亚洲和热带非洲分布、东亚分布、世界分布、热带亚洲分布及北温带分布）以东亚分布为主。未发现经典的铜藓（Copper Mosses）。

Abstract:Bryophyte species were investigated in Tangdan Copper Mine site in Dongchuan district of Kunming City, Yunnan Province. Twenty–two species belonging to 16 genera (Barbula, Gymnostomum, Didymodon, etc.) of 6 families (Pottiaceae, Bryaceae, Brachytheciaceae, Thuidiaceae, Ditrichaceae and Entodontaceae) were found, 59% of which was Pottiaceae as a dominant family. Sixty-eight percent of the species lived on cupreous rocks covered with patina, while 32% grew on cupreous soil. The species were divided into 3 life forms: short turfs (68%), high turfs (14%) and wefts (18%). There were 7 areal types (Eastern Asia and North America, Endemic to China, Tropical Asia and Tropical Africa, Eastern Asia, Cosmopolitan, Tropical Asia, North Temperate), among which Eastern Asia was dominant. The classical “Copper Mosses” were absent.
