摘　　要：通过采集巨野县318件浅层地下水样品,分析了浅层地下水34项指标的含量特征,并对其进行了环境质量评价与成因分析。结果表明：研究区浅层地下水中CN^-未检出,其他指标均有检出;pH值范围在6.78-8.21之间,主要为淡水和微咸水;浅层地下水中As、Hg、Se、Cd、CN^-、Cr^6＋、Co、Cu、Be、Zn、Pb、Ni、pH、Mo、Ba 15项指标基本符合《地下水质量标准》中Ⅲ类水规定的阀值,而影响研究区浅层地下水质量的主要因子是NO^2-、F^-、I^-、Mn、Fe、总硬度、溶解性总固体;浅层地下水中Ca^2＋、Mg^2＋含量较高是造成溶解性总固体（TDS）和总硬度含量较高的原因,空间上TDS与该地区工业生产密切相关,而第四系沉积环境和水文地质条件是Fe、Mn、F离子含量超标的主要原因。This paper collects 318 samples from shallow groundwater in Juye County area,tests 34 indicators,studies the content of each index in the shallow groundwater and does environmental quality assessment and genesis analysis of the shallow groundwater.The results show CN^-is not detected while other indexes are detected.The analysis shows that pH of shallow groundwater in the study area is in the range of 6.78 to 8.21,the shallow groundwater mostly belongs to fresh water or brackish water,and the concentration of As、Hg、Se、Cd、CN^-、Cr^6＋、Co、Cu、Be、Zn、Pb、Ni、pH、Mo、Ba in the shallow groundwater is basically meeting the threshold of theⅢ class water in Quality Standard for Ground Water.The mainly factors influencing the quality of the shallow groundwater are NO2^-,F,I,Mn,Fe,total hardness and total dissolved solids.The high content of Ca and Mg is one of the causes of higher solubility in total solid content and total hardness,and the distribution of total dissolved solid in space closely relates to the regional industrial production.The Quaternary sedimentary environment and hydro-geological conditions are the main causes of the exceeding standard of iron,manganese and fluoride.
