| 摘 要： | 依据银川地区的水文地质条件将其地下水系统划分为单一潜水和多层结构的潜水———浅层承压水,分析地下水系统中主要离子、矿化度和水化学类型的特征及其变化,表明,潜水含水层自西向东,自北向南水质变差,矿化度升高,主要离子的变化特征与矿化度基本一致,水化学类型由HCO3.SO4-Ca.Mg向SO4.Cl-Na.Mg过渡。浅层承压水含水组的地下水质变化特征和潜水基本一致。

| Abstract: | In accordance with hydrogeological condition of Yinchuan region,two groundwater systems are presented in the paper,they are the phreatic water systems with single-layer structure and phreatic water together with shallow confined groundwater system.The component of the major ions,mineralization degree and chemistry types and their variations of the above-mentioned groundwater systems are analyzed.The results show that,from West to East and from North to South,water quality degrades gradually,mineralization degree raises,and the variations of the major ions and mineralization degree are similar,water chemistry type transfer from HCO3·SO4-Ca·Mg to SO4·Cl-Na·Mg.The variation characteristics of shallow confined groundwater are similar with phreatic water. |
