Abstract: 13 species of dominant plants naturally growing in the wastelands of Fushun Hongtoushan copper mine (original tailings, waste dump, tailings covered with domestic wastes) are investigated, and the heavy metals Cu, Zn, Pb, Cd content in aboveground and underground parts of these dominant plants are checked out. The accumulation ability and tolerance of four heavy metals on these dominant plants are researched. According to the research, the artemisia umbrosa, flos rosae davuricae and spiraeathunbergii selected from the original tailings, the sedge, larch and artemisia sieversiana selected from wate pile dumps and the nicandraphysalodes and chenopodium glaucum selected from domestic wastes dump are chosen as the pioneer species for Hongtoushan copper mine.
