| Abstract: | According to the propagation characteristics of heavy metals, the partial differential equation is constructed to determine the heavy metal in the surface soil pollution source model. Using the numerical integration and parameter estimation, the unit volume of heavy metal pollutants in the quality is obtained. At the same time, by use of MATLAB software to fit two variables quadratic equations, the numerical solution is derived, which is more convenient and accurate for the determination of the heavy metal pollution source location. |
