抚顺红透山铜矿废弃地植物重金属耐性研究

Research on Tolerance of Plants to Heavy Metal is Wastelands of Fushun Hongtoushan Copper Mine

调查了抚顺红透山铜矿废弃地(原始尾矿库、排土场、覆盖生活垃圾的尾矿库)中自然生长的13种优势植物,取样检测了这些优势植物地上部分和地下部分中重金属Cu,Zn,Pb,Cd的含量,并研究了这些优势植物对4种重金属的富集能力和耐性。根据检测和研究结果,在原始尾矿库中选取野艾蒿、山刺玫和珍珠梅,在排土场中选取薹草、落叶松和大籽蒿,在覆盖生活垃圾的尾矿库中选取假酸浆和灰绿藜作为红透山铜矿废弃地植被恢复的先锋物种。

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 railings, the sedge, larch and artemisia sieversiana selected from ware pile dumps and the nicandraphysalodes and chenopodium glaueum selected from domestic wastes dump are chosen as the pioneer species for Hongtoushan copper mine.
