摘  要:随着城市的不断扩张与建设,城市人口的不断汇聚导致城市环境质量不断面临新的问题,迫切需要对城市表层土壤开展调查研究以获得污染来源和污染区域。文章利用X射线荧光仪采集表层土壤Cr、Ni、Cu、Zn四种重金属污染元素的含量,利用潜在生态危害指数法对测量数据进行分析,得出了区域内四种元素含量等值线图和潜在危害指数等值线图,为污染源监测控制和治理提供参考。With the continuous expansion and construction of the city and the continuous convergence of urban population, the urban environmental quality is constantly facing new problems. It is urgent to investigate and study the urban topsoil in order to obtain the pollution source and pollution area. In this paper, the contents of Cr, Ni, Cu and Zn in surface soil were collected by X-ray fluorescence instrument, the measured data were analyzed by potential ecological hazard index method, and the content contour map of four elements and potential hazard index contour map in the region were obtained, which provided a reference evidence for pollution source monitoring,control and treatment.
