In order to visually show the pollution scope,pollution degree and pollution diffusion process of the heavy metal pollution element mercury(Hg)in the target area,and solve the problem that the result of pollution diffusion is different from the traditional pollution diffusion model due to the influence of wind,an improved pollution diffusion model is proposed according to the actual situation of the target area.To simulate the true diffusion process of heavy metal pollution in the soil of the target area more in line with the actual situation,we took into account the general diffusion law of heavy metals in the soil and the influence of wind direction and wind speed on the pollution diffusion process.After completing the improvement of the pollution diffusion model algorithm,combined with the Cesium open-source framework to visualize the pollution process of the heavy metal pollutant Hg in the target area on the three-dimensional earth,the diffusion process of Hg element in the target area was dynamically displayed based on the traditional diffusion model combined with wind field factors on the front end of the Web.
