With the rapid development of economic and the increasingly
urban populations, the impacts of humans’
activities on the environment quality of the city is prominently increased.
In this study, for the spatial distribution and concentration of the sampling
points of heavy metal elements in the city, evaluate soil heavy metal pollution
by using Single-factor index method, Nemero index method and cumulative index
method, determine the main causes of pollution in each region by the cluster
analysis method and the principal component analysis method. Finally, we get
the position coordinates of pollution sources in the city by building and solving
the three dimensional partial differential model of migration of heavy metal
pollutants in soil environment system. In order to provide better research for
the evolution model of the urban geology environment, we collected more information
and evaluate the advantages and disadvantages of the models.
