城市表层土壤重金属污染分析优化模型
Optimization model for analysis of heavy metals pollution in urban topsoil
摘要
Abstract
To analyze the problem of heavy metal pollution in urban topsoil,the spatial distribution map of the heavy metal is drawn and the spatial distribution model is established by using mass of data of spatial distance and heavy metal element content and Kriging interpolation method.Moreover,the evaluation model of the heavy metal pollution degree is established,and the pollution degrees of different regions of five categories are evaluated by using individual pollution index and Nemerow comprehensive index method.It is found that the crucial causes for the heavy metal pollution are industrial production activities.Lastly,the equation model of the convection-dispersion-adsorption is established based on analyzing the propagation characteristics of the heavy metal pollutants.关键词
