摘　　要：城镇化对很多地区的地下水水质造成了严重破坏,研究其破坏机制及其主要因素可为城市地下水资源开发、保护和修复提供参考。以河南省永城市为例,在对比分析实地调查采样数据和历史数据的基础上,运用多种方法综合研究城镇化对浅层地下水质的破坏机制及其主要影响因素。结果表明:随着城镇化的发展,永城市浅层地下水水化学类型趋向复杂化;城镇化初期影响浅层地下水水质的主要组分为农业活动带来的NO-3浓度上升,而城镇化高速发展期变为工矿业废水排放带来的SO42-。综合分析可知:城镇化对浅层地下水水质的影响在不同阶段呈现出不同的特征,且影响因素也不同,因此应根据城镇化发展的程度和阶段开展有针对性的地下水污染防治工作。Urbanization has caused serious damage to the groundwater quality in many areas.The study on the da-mage mechanism and its main factors can provide some references for the development,protection and restoration of urban groundwater resources.Taking Yongcheng city of Henan Province as an example,based on the comparative analysis of field survey sampling data and historical data,this paper uses a variety of methods to comprehensively study the mechanism and main influencing factors of urbanization on shallow groundwater quality.The results show that with the development of urbanization,the chemical composition of shallow groundwater has become more complex,which is mainly caused by the increase of NO-3 from agricultural activities in the early stage of urbanization and by the one of SO42- from industrial and mining waste water in the rapid development stage.Therefore,for the shallow groundwater,different stages show different characteristics resulting from different factors;different mea-sures on prevention and control should be taken according to the urbanization development.
