This paper will focus on the establishment, parameter determination, simulation, and sensitivity analysis of one-dimensional multi-component solute transport models. First, the basic theory of one-dimensional multi-component solute transport model is introduced, including the mass conservation equation, advection equation, diffusion equation, and reaction equation. Secondly, the method of parameter determination is discussed, the common parameter inversion algorithm is explored, and a parameter inversion strategy combining swarm intelligence optimization algorithm and Bayesian method is proposed. Then, combined with the actual situation of the contaminated site, simulation calculation and error analysis will be carried out. Finally, sensitivity analysis will be carried out to explore the impact of different parameters on the model results, improve the credibility and predictive ability of the model, and provide decision support for the remediation of contaminated sites and environmental protection.【Key words】one-dimensional multi-component, solute transport, model, parameter inversion, sensitivity analysis
