摘　　要：通过对样本数据的分析,采取三维傅里叶方式变换,并根据实际情况设定扩散过程中主要的变化参数,建立重金属扩散模型,采用计算机连续模拟重金属污染的扩散过程,最终确定重金属污染源的位置。该模型精度高,实用性强。该方法对城市可持续发展有一定指导意义。Through analysis of sample data,adopting three dimensions Fourier transform way,according to the realistic situation and set main variation parameters during diffusion process,a heavy metal diffusion model was established.By using computer continuous simulation of heavy metal pollution diffusion process,the position of heavy metal pollution sources was eventually determined.The model has high,practical applicability characteristic.This method has a great significance for urban sustainable development.
