Abstract:
Setaria viridis and Kochia scoparia var.sieversiana collected from the Fifth，Jiulong and Wutongzhuang of Fengfeng coal mining areas were using as research subjects.The contents，transport coefficient and enrichment coefficient of Pb，Cu，Zn，Cr and Mn in aboveground and underground parts of Setaria viridis and Kochia scoparia var.sieversiana and rhizosphere soil collected from the Fifth，Jiulong and Wutongzhuang of Fengfeng coal mining areas were studied，respectively.In order to explore the differences of the accumulation of heavy metals between arbuscular mycorrhizal and non mycorrhizal plants around coal mining areas.The results showed that the heavy metal accumulation of mycorrhizal and non mycorrhizal plants was different in three mining areas.The contents，transport coefficient and enrichment coefficient of Pb，Cu，Zn，Cr and Mn in S.viridis were higher than those in K.scoparia var.sieversiana on the whole.The content of aboveground parts，transfer coefficient and enrichment coefficient of Pb and Cu in S.viridis were higher those in K.scoparia var.sieversiana.The content of aboveground parts，transfer coefficient and enrichment coefficient of Pb in S.viridis were 22.98 mg?kg-1，1.25 and 0.14，respectively，which were 1.19，1.24,1.26 times higher than those in K.scoparia var.sieversiana，and the average index of Cu in S.viridis were 35.68 mg?kg-1，1.90，and 0.28，which were 1.22，2.25,1.30 times higher than those in K.scoparia var.sieversiana.The content of aboveground and underground parts，transport coefficient and enrichment coefficient of Zn，the content of aboveground parts，soil of rhizosphere content，transfer coefficient and enrichment coefficient of Cr，the content of aboveground and underground parts，and enrichment coefficient of Mn in S.viridis were higher than those in K.scoparia var.sieversiana.Moreover，the absorption and accumulation of heavy metals in S.viridis were also higher than those in K.scoparia var.sieversiana even in the same coal mining area.Further，the double-factor main effects analysis were conducted on the mining area and plants.The main effect factors of Pb and Mn were the coal mining area，while those of Zn and Cu were plants.
