JIANG Hong et al(Bijie University,Bijie,Guizhou 551700)  
[Objective] The research aimed to provide the reference for the application of the bryophytes in the vegetation restoration of the heavy metals in lead and zinc mining waste land in Bijie Area.[Method]The comprehensive investigation,the collection,and the identification of the bryophyte in lead and zinc mining waste land in Bijie area were carried out.And the bryophytes in lead and zinc mining waste land were compared with those of copper mine,gold mine and mercury mine.[Result]30 mosses species in 14 genera of 4 families were reported at the region.There were two dominiant families that were pottiaceae and bryaceae in the region.And species richness of the bryophytes was the lowest in lead and zinc mining waste land,and it was-0.958 0.The similarity coefficient of the species was the lowest,too.It was 13.56%.Short turfs was the dominant life-forms of the bryophytes in lead and zinc mining waste land.At the same time,there were 4 species of widespread bryophytes found in the four mine.They were Barbula fallax Hedw.,Bryum dichotomum Hedw.,Anomobryum filiforme(dicks.) husn.,Pohlia proligera(kindb.) arn.broth.and Didymodon rigidulus Hedw.[Conclusion]These species provided a better material of vegetation restoration,which used in bryophytes study in lead and zinc mining waste land.
