英文摘要	Parameter estimation is the key job of mathematics simulation and calculation. Based on the seepage mechanics of unsaturated soil and the theory of solute transport, the contaminant transport model considering adsorption, desorption and immobile water in one-dimension was established, and was taking as the awaiting inversion model. The least-squares technique was used to establishing objective function, and the Newton method was used to calculate iterative problem of the model parameters. For checking the optimization inversion method of model parameters, the laboratory experiment was done for obtaining experimental values of contaminant concentration. The comparison curves showed that the breakthrough curves calculated by using the inversion parameters are in good agreement with the data derived from laboratory experiment. It indicates that optimization inversion method in this paper is feasible, and the forecast result is dependable.
