Abstract: In the soil environment，the material transmission mechanism significantly affects the migration of pollutants. Through analyzing the numerical solutions of the problem of pollutant migration, the time-space law of the transmission of organic pollutants in soil can be mastered, which has both theoretical and practical significance. Based on the convectiondiffusion theory, the general mathematical model of the migration of pollutant in soil was established; and then the convectiondiffusion questions in various specified initial and boundary conditions were numerically simulated using COMSOL software.Three typical models of pollution sources emission were calculated, which include stably continuous, index change, instantaneous release.The influences of various parameters in model on calculation results were compared, such as diffusion, convection, adsorption and degradation parameters.Finally,a correlation analysis and discussion was made on calculation results of the pollutant concentration distribution.
