Point Propagation Model of Pollution Sources of Heavy Metals in the Surface Soil

摘要

The soil pollution caused by heavy metal is difficult to treat. Many scientists and researchers arefocusing on solving the problem in recently years. By probing into the law of diffusion and the law ofconservation of mass, we establish the point propagation model of pollution sources of heavy metalsand come to the distribution characteristics function of the local area the concentration of heavy metalsin soil. Finally, the proposed point propagation model is utilized to establish a method for determiningthe point pollution sources.
