摘　　要：选择合适的模拟方法预测重金属的迁移对于防治重金属污染具有重要意义。介绍土壤重金属的垂向迁移和水平迁移2种方式,比较了垂向迁移中的经验模型、分相模型和整体模型,以及水平迁移中的SWAT模型、随风迁移模型的优缺点及其影响因素,探讨了这些模型在矿集区重金属迁移模拟中的适用性,为矿集区选择合适的土壤重金属迁移模拟方法提供了科学依据。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.
