Abstract: By means of ecological survey and laboratory analysis, a comprehensive study on species number, distribution, index of atmospheric purity (IAP), content of Pb, Zn, Cu, Cd, total Spollutants in bryophytes, and their relationships with environmental pollution at five monitoring sites of Anshan city were carried out.In the seriously polluted region, including Anshan Steel & Iron Company, the species number of bryophytes was less than five; the IAPvalue was smaller than five; the pollutant content (mg·kg^-1 )in bryophytes was as follows: Pb(112～149), Zn(401～477), Cu(35.8～38.5), Cd(2.45～3.53), S(2200～3100).In the polluted region, including Lishan Park and Eryijiu Park, the species number of bryophytes ranged from 15 to 30; IAPvalue ranged from 5 to 25; the pollutant content was as follows: Pb(31.2～44.6), Zn(120～199), Cu(9.40～17.6), Cd(1.02～2.42), S(1400～2600).In the basically unpolluted region, including Lieshi Lingyuan and Qianshan, the species number of bryophytes was more than40; IAPvalue was larger than30; the pollutant content was as follows: Pb(15.4～25.6), Zn(84.3～135), Cu(5.24～11.5), Cd(0.64～1.99), S(800～2100).
