摘　　要：潍坊市是全国重点缺水城市之一,水资源是限制其经济发展的因素之一。为了探明当地地下水水源地分布状况和水环境质量,本文选取了6个供水水源地为研究对象,采集代表性水样55个并分析了主量离子浓度及TDS,在此基础上,运用Piper三线图图示法和离子比例系数法系统研究了地下水水化学特征和演化规律。结果表明:(1)潍坊东侧水源地地下水阳离子以Ca^(2+)、Na^(+)为主,无明显优势阴离子,从南向北水化学类型由HCO_(3)·SO_(4)·Cl^(-)Ca型向HCO_(3)·SO_(4)·Cl^(-)Ca·Na型转变;(2)水岩作用、蒸发浓缩作用是控制这6个水源地地下水化学组成的主控因素,硅酸盐岩和碳酸盐岩溶滤作用是水岩作用的主要类型;(3)青州赤涧和大郇水源地地下水中Ca^(2+)、HCO_(3)^(-)主要来源于方解石溶解,并且两地的地下水中溶解来源具有一致性,可能来自同一灰岩。Weifang is one of the key water-deficient cities in China,water resource is one of the factors limiting the economic development.In order to explore the distribution of local groundwater and water quality,6 water supply sources were selected as research objects,55 representative water samples were collected and analyzed the main ion concentration as well as TDS.Piper three-line diagram method and ion ratio coefficient method were used to systematically study the hydro-chemical characteristics and evolution of groundwater.The results show that:①The cations of groundwater on the east side of Weifang are mainly Ca^(2+)and Na^(+),without obvious dominant anions,and the hydrochemistry type was transformed from HCO_(3)·SO_(4)·Cl^(-)Ca type to HCO_(3)·SO_(4)·Cl^(-)Ca·Na type from south to north.②Water-rock interaction and evaporation are the main factors controlling the chemical composition of groundwater,and silicate rock and carbonate karst filtration are the main types of water-rock interaction.③Ca^(2+)and HCO_(3)^(-) in the groundwater of Chijian and Dahuan in Qingzhou mainly come from calcite dissolution,and the dissolution sources of groundwater in this two places are consistent,which may come from the same limestone.
