Abstract: To reveal the influence of different vegetation restoration modes of coal gangue mountain on the soil heavy metal migration rule in wind-blown sand area, the coal gangue mountain in wind-blown sand area of northern Shaanxi Province was used as the research object, and the soil mechanical composition, pH, electrical conductivity, organic matter and cation exchange capacity at 0~20 cm and 20~40 cm depth were measured under different planting and restoration modes of Medicago sativa, Caragana korshinskii, Juniperus sabina, Amorpha fruticosa, as well as copper (Cu), zinc (Zn), lead (Pb), cadmium (Cd), chromium (Cr) 5 kinds of heavy metal elements content and existence form. The results showed that among the 4 restoration modes, Medicago sativa restoration mode had finer soil texture and the best effect, and the deep soil matrix was more stable. The average content of Cu, Zn and Pb in deep soil is higher than that in surface soil, and the residual state of heavy metals in surface soil is higher than that in deep soil, indicating that the closer the distance from coal gangue, the higher the content of heavy metals in soil. Soil heavy metals Cu, Zn and Cr are mainly in residual state, and Cu is positively correlated with Zn and Cr, indicating that they may have the same source. The effects of soil physicochemical properties on heavy metal content were ranked in the order of CEC＞SOM＞pH＞TDS.
