The comparison of simulation methods for soil heavy metal movement in the ore concentration area

It is very important to choose a proper simulating method to predict transformation and migration process of heavy metals in soil so as to prevent and remediate pollution of heavy metals. The authors investigated vertical migration and lateral transfer of heavy metals, and analyzed the advantages and disadvantages of such models as the empirical model, the facies-separation model and the holistic model in vertical migration as well as SWAT and the migration model with the wind in lateral transfer, with a discussion on their suitability in the ore concentration area. The results obtained by the authors provide a theoretical foundation for the choice of the simulation method for soil heavy metal movement in the ore concentration area.
