摘要
In recent decades,mathematical modeling has been widely utilized in sample data analysis.This paper mainly focused on discussing heavy metal pollution caused by 8 major elements about 5 sorts of districts with different functionality.Evaluating the impact of human activity on the top soil heavy metal pollution can be reached by the given sample data.To begin with,Kringing′s method of interpolation enabled us to visualize while simulate the situation.moreover,we use simulated annealing and artificial neural network to analyze the degree,original location,causes and spatial distribution of the pollution.According to our results,this paper accurately deduced the location of sources of pollutions and the distribution of heavy metal elements while simulated the process of dissemination.
