摘　　要：为确定新疆阿克苏地区地下水优先控制污染物,结合潜在危害指数法和综合评分法对新疆阿克苏地区地下水中9项评价指标进行了优先控制污染物筛选,利用GIS软件分析了阿克苏地区地下水优先控制污染物的空间分布规律,并将地下水中各优先控制污染物与土地利用类型在空间上进行叠加,结合土地利用类型与主成因分析法确定了阿克苏地区地下水优先控制污染物的来源。结果表明:阿克苏地区地下水优先控制污染物包括苯并[a]芘、As、Pb和Cd,其中苯并[a]芘污染主要由人类生活因素造成,As和Cd污染主要由自然富集因素造成,Pb污染主要由农业活动因素造成。In order to determine the priority control pollutants in groundwater of Aksu Prefecture,Xinjiang,this paper combines the potential hazard index method and the comprehensive scoring method to screen the priority control pollutants of nine groundwater evaluation indexes in the study area.The spatial distribution law of priority control pollutants in groundwater is analyzed by using GIS software,and their source is revealed by overlapping each priority control pollutant in groundwater and land use type in space,and combining land use type with the main cause analysis method.The results show that the priority control pollutants in groundwater of Aksu Prefecture include benzo[a]pyrene,As,Pb and Cd.Among them,human life is a main factor to affect benzo[a]pyrene,natural enrichment is a main factor to affect As and Cd,and agriculture is a main factor to affect Pb.
