摘　　要：本文分析了某城区土壤重金属的污染特征和来源。首先,利用克里格插值方法绘制某城区8种重金属元素浓度的空间分布图;其次利用单项污染指数法和内梅罗综合污染指数法评价各功能区8种重金属元素的污染程度;最后,利用因子分析法分析土壤重金属污染原因,结果表明主要由交通、工业和居民生活垃圾等三方面原因造成。This paper analyses Characteristics and Sources of the topsoil heavy metal Pollution in certain city.First,the spatial distribution maps of the concentration of eight heavy metals were drawed by kriging interpolation method.Second,the pollution level of eight heavy metals in each functional area were evaluated through the single factor index method and the overall pollution index nemerow method.Finally the research result of factors analysis indicates there are three respects in main sources of soil heavy metal pollution,which involve the pollution sources of traffic pollution sources,industrial pollution sources,resident＇s life pollution sources.
