Abstract:In this paper, a typical lead-zinc mine as the research object, By mining the impact on the surrounding soil were investigated, analyzed the mechanism of the mining area and causes of soil pollution. through established the migration experimental model of heavy metal pollution, And using partial least squares (PLS) to establish the linear regression curve equation migration,which reached the main pollution elements (cadmium) Cd, (lead) Pb, (Zn) Zn migration characteristics, According to the result,which determined the scope, extent and area of mining heavy metal contaminated soil and provided for the scientific management of mine contaminated land.
