摘　　要：基于某城市城区土壤地质环境调查得到的城市不同功能区、不同海拔位置的表层土壤中8种主要重金属浓度为样本,评价了该城区内不同区域重金属的污染程度;通过数据分析了重金属污染的主要原因;基于重金属污染物的传播特征,建立了确定污染源的位置的数学模型;为了更好地研究城市地质环境的演变模式,指出应收集更多信息以及利用这些信息如何建立模型解决问题.Based on eight major concentrations of heavy metals in soil sample, which were got from the geological environment of a city urban soil surveys for different functional areas of the city and different location of the surface at altitudes, heavy metals pollution degrees of the different areas within city limits were evaluated. Through data analysis, the major reason of heavy metals pollution was given. Based on the propagation characteristics of heavy metal pollutants, the mathematical model for determining the location of pollution sources was established. In order to better study the evolution of urban geological environment model, it was pointed out that more informations should be collected and how to use the informations to establish models to solve problems.
