摘　　要：文章针对城市表层土壤的重金属污染问题进行了分析。对某城市土壤地质环境问题调查和收集数据后,利用数学建模的方法和Matlab软件求解。首先采用griddata插值法和地积累指数法分析了该城区的重金属污染程度;再通过聚类分析法分析了重金属污染的主要原因;最后运用主成分分析法综合分析,确定了污染源的位置,这对于土壤重金属污染的预测和控制有重要意义。The heavy metal pollution of urban surface soil was analyzed in this paper.After the investigation and data collection of soil geological environment problems in a city,mathematical modeling method and Matlab were used to solve them.Firstly,griddata interpolation method and ground accumulation index method were used to analyze the heavy metal pollution degree of the city.Then the main causes of heavy metal pollution were analyzed by cluster analysis method.Finally,principal component analysis was used to determine the location of pollution sources,which is of great signif icance for the prediction and control of soil heavy metal pollution.
