| 摘 要： | 对某城市表层土壤中As、Cd、Cr、Cu、Hg、Ni、Pb、Zn等8种重金属元素的含量进行了采样分析,采用域法识别特异值进行数据处理。采用坐标平移法,修正高斯扩散方程,利用MATLAB软件进行拟合,得到了这8种重金属污染源的空间位置坐标。

| Abstract: | This article analyzed the contents of 8 kinds of heavy metal elements （ As, Cd, Cr, Cu, Hg, Ni, Pb, Zn） in the topsoil samples of a city , and treated the obtained data by using the threshold method to recognize the outliers .The method of coor-dinate translation method was used to amend the Gaussian diffusion equation .By using MATLAB software to simulate , we acquired the spatial coordinate locations of 8 kinds of heavy metal pollution sources in the soil . |
