摘要
随着城市化建成的逐渐加快,频繁的人类活动加剧影响着水环境,研究城市地下水环境可以有针对性地对城市地下水资源进行系统科学的监测和保护。本文将郑州市区浅层地下水作为主要研究对象,综合运用数理统计、Piper三线图、Gibbs图和离子比值等方法分析研究区水化学特征及其影响因素,研究结果表明:郑州市区地下水表现为弱碱性、中等矿化度,地下水中主要离子以HCO^(-)_(3)、Ca^(2+)、Na^(+)含量占优势,地下水化学类型包括Ca·Mg-HCO_(3)和Ca·Mg-SO_(4)型,地表水表现为Ca·Mg-SO_(4)型水。岩石风化是影响郑州市区地下水化学特征的主要控制因素,同时溶滤作用、阳离子交换作用以及人类活动对地下水化学特征的形成也有影响。本研究为该地区水资源的开发利用与保护提供了科学依据。
With the gradual acceleration of urbanization,frequent human activities intensify and affect the water environment.The study of urban groundwater environment can scientifically monitor and protect urban groundwater resources to ensure the sustainable development of the resources.The hydrochemical characteristics and the influencing factors of the shallow groundwater in Zhengzhou downtown were analyzed with mathematical statistics,Piper diagram,Gibbs diagram and ion ratio method.The results show that the groundwater in the study area is weakly alkaline and medium salinity;the main cations and anions of groundwater are Ca^(2+),Na^(+)and HCO^(-)_(3);the hydrochemistry types of the groundwater are mainly Ca·Mg-HCO_(3) and Ca·Mg-SO_(4);the dominant hydrochemistry type of the surface water is Ca·Mg-SO_(4).The groundwater chemical composition is mainly controlled by rock weathering,dissolution,cation exchange and human activities.This research provides a scientific basis for the development,utilization and protection of water resources in the region.
