为直观展示目标区域重金属污染元素汞(Hg)的污染范围、污染程度、污染扩散的过程,解决污染物在扩散过程中因受到风力的影响而产生与传统污染扩散模型结果有所出入的问题,针对目标区域的实际情况提出一种改进的污染扩散模型.在考虑到土壤重金属一般扩散规律的同时兼顾风向和风速等因素对污染扩散过程的影响,以求模拟得到目标区域土壤重金属污染更加符合实际情况的扩散过程.在完成对污染扩散模型算法的改进之后,结合Cesium开源框架实现在三维地球上对目标区域土壤重金属污染物Hg的扩散过程的可视化,在Web前端动态地展示研究区域Hg元素在传统扩散模型基础上结合风场因素的扩散过程.
SIMULATION OF SOIL HEAVY METAL POLLUTION DIFFUSION PROCESS COMBINED WITH WIND FIELD
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.
