摘　　要：应用地质、水文地质、水化学、地球化学等调查技术手段阐明聊城市城郊浅层地下水特征,并重点分析了地下水水质影响因素,研究结果表明聊城市城郊浅层地下水水质相对较差,以Ⅳ类水为主,主要超标指标为总硬度、TDS、氟化物、氯化物、硫酸盐、硝酸盐、亚硝酸盐和氨氮,无重金属元素超标现象,丰水期水质略优于枯水期,农业施肥是研究区浅层地下水主要的污染途径,建议加强区域的的农业化肥施用管理和市政自来水管道建设,区域居民选择饮用市政供水。Geology,hydrogeology,water chemistry,geochemistry and other survey techniques were used to investigate the characteristics and genesis of shallow groundwater in the suburbs of Liaocheng City.The results show that the shallow groundwater quality in the suburbs of Liaocheng City was poor,which mainly based on Class IV water.The over-standard indicators were total hardness,TDS,fluoride,chloride,sulfate,nitrate,nitrite and ammonia nitrogen.The water quality in wet season was slightly better than the dry season.Agricultural fertilization was the main pollution route of shallow groundwater in the study area.It was recommended to strengthen the chemical fertilizer application management and municipal water supply pipeline construction.The regional residents choose to drink municipal water supply.
