ABSTRACT
Propagation characteristics of pollutants are often used to analyse pollution degree and center offset. We find out that pollutants spread from center to surrounding, and with the increase of the distance, the degree of pollution decreased. Given the present conditions, heavy metal pollutant move through the soil moisture migration, and it is also influenced by the soil matrix, physical and chemical properties of soil solute, and other chemicals in the soil. If only consider some of these factors, can it calculate the concentration of each direction by establishing low dimensional partial differential model [1].
