ABSTRACT

Modeling is an efficient way to predict the heavy metal migration process, areas and amount. Nowadays, the soil heavy metal migration models mainly include empirical model, separated model and holistic model, such as Hydrus-ID model (Minh et al. 2009) and LECHM model (Legret et al. 1999). However, these models all have limitations in improving simulation precision (Sandy et al. 2009). Therefore, It is necessary to build an appropriate model to predict soil heavy metal migration, which would be helpful for soil heavy metal pollution prevention and remediation.
