The spatial distribution and propagation of heavy metal pollutants in soil

While heavy metal pollutants are becoming more and more serious in urbanization process, it has practical value to determine the source and distribution of pollutants. Based on Kriging interpolation, This paper establishes a model to visually analyze the spatial distribution of heavy metal pollutants area with GS + software. Based on the rule of heavy metal diffusion, the classical Gaussian diffusion model and computer simulation are adopted to simulate diffusion process, and a suspicious pollutants source point is found compared with realistic observed value. The results using the model established shows that it is in accordance with the realistic observation.
