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.
