摘　　要：With mixed gangue,coarse gangue and washed gangue as well as the maize in the reclaimed land in Luling Mine of Huaibei as the research object,the biology migration and distribution characteristics of trace elements in the reconstructed soil with different types of coal gangue filling were studied,the contents of Cu,Pb,Zn,Sn,Hg,Cd and Cr were determined,and the distribution characteristics of the trace elements in the coal gangue and different organs of the maize were analyzed.The results showed that the contents of trace elements were the highest in washed gangue and the least in coarse gangue in the gangue used for the reclamation,and there were significant differences in the enrichment ability of trace elements in different organs of maizes that were planted in reclamation land,of which fruit was weaker than other organs,while leaf presented strong absorption ability.With mixed gangue, coarse gangue and washed gangue as well as the maize in the reclaimed land in Luling Mine of Huaibei as the research object, the biology migration and distribution characteristics of trace elements in the reconstructed soil with different types of coal gangue filling were studied, the contents of Cu, Pb, Zn, Sn, Hg, Cd and Cr were determined, and the distribution characteristics of the trace elements in the coal gangue and different organs of the maize were analyzed.
