| Abstract: | For the problem of heavy metals pollution diffusion in urban surface soil,cluster analysis is utilized to determine that heavy metal pollutants are mainly concentrated in industrial area firstly.Then,various metal pollutants correlations are studied by factor analysis to find some kinds of metal pollutants are homologous while higher positive loads between each other.At last,Gauss cloud-cluster model is established to simulate metal pollutant diffusion.The parameters solution of the model is based on nonlinear regression.Pollution source three-dimensional coordinate can be obtained through the solution of multivariate linear equations.The effectiveness of the model and the algorithm are proved by simulation experiments on practical data. |
