摘要/Abstract

摘要： 渭河流经陕西华阴、华县(二华)段,通过对"二华"地区浅层地下水取样分析,系统研究其地下水化学成分的空间变化及演变规律。结果表明:"二华"地区浅层地下水主要接受秦岭山前地下水的补给,靠近渭河沿岸地区,接受渭河的侧向补给。地下水的补给、径流、排泄区水化学类型主要从HCO₃·SO₄-Ca·Mg经SO₄·HCO₃-Na·Ca过渡到SO₄·Cl-Na型;其矿化度、硬度逐渐升高,在地下水漏斗处达到最大值;Cl^-,Mg²⁺和Na⁺高盐分离子逐渐累积,水质总体向咸化方向发展。

Abstract: The Weihe River flows through Huayin City and Huaxian County. According to the analyzed results of shallow groundwater samples collected in Huayin City and Huaxian County, in this paper the spatial hydrochemical properties and their evolution of groundwater are studied systemically. The results show that shallow groundwater in the study area is mainly recharged by groundwater from the Qinling Piedmont, and it in the areas along the riverbanks relies mainly on the lateral recharge of the Weihe River. The hydrochemistry type in the areas of groundwater recharge, runoff and discharge changes from HCO₃·SO₄-Ca·Mg to SO₄·HCO₃-Na·Ca and then to SO₄·Cl-Na; the salinity and hardness of groundwater increase gradually and reach to their maximum values in the funnel-shaped zone of groundwater; Cl^-, Mg²⁺ and Na⁺ are gradually accumulated, and groundwater quality trends to salinization. The study results can provide the references for understanding the effect of the Weihe River on groundwater quality in the areas along the river and for rationally utilizing groundwater resources in the study area.

Key words: Huayin City, Huaxian County, shallow groundwater, groundwater chemical composition, spatial variation, Shaanxi Province, Weihe River
