| 摘 要： | 为研究常见地表污染源对地下水造成的影响,开展了某傍河区域的研究。在对傍河研究区开展野外调查、钻探取样分析等工作的基础上,从水化学角度对研究区地下水进行了系统分析,揭示了研究区内污染河水与地下水并没有明显的水力联系,深、浅含水层水力联系微弱;浅层地下水化学成分的形成以溶滤作用为主,并存在阳离子交换作用,易受到地表污染源及人为活动的影响;深层地下水化学成分的形成主要受到大区域水文地质环境演化的影响。

| Abstract: | This study specified a riparian site to research the effect of common surface pollutant sources to groundwater.A field investigation and a series of hydrographic geological drilling work,sampling campaigns were carried out in the riparian site.A systemic study in respect of hydrochemistry was conducted on the basis of these work.The results demonstrate that there is no obvious hydraulic connection between the polluted river and groundwater,and the hydraulic connection between the deep aquifer and shallow aquifer is weak.The chemical compositions of the shallow groundwater are mainly caused by the effect of mineral dissolution and cation exchange processes.The shallow groundwater is vulnerable to surface pollutant sources and anthropogenic activities.The chemical compositions of the deep groundwater are domained by the effect of large scale evolution of hydrogeological environment. |
