摘 要：
运用Piper三线图、离子比例系数和数理统计等方法,系统地分析了鲁北浅层地下水的空间分布及水化学特征。结果表明,浅层地下水的水化学类型复杂多变,从内陆至滨海地下水由淡水逐步演化为微咸水、咸水、盐水;常规离子组分中Cl-的变异系数最大,其次是Na+,HCO-3的变异系数最小;滨海地区浅层地下水γNa/γCl多介于0.8~0.9之间,而内陆地区γNa/γCl一般大于1.0;局部地段内陆咸水γNa/γCl小于0.5,属Cl·SO4-Na型或Cl·SO4-Na·Mg型咸水/微咸水,多呈点状分布;研究区沿海地区浅层咸水多以海成盐化咸水为主,内陆咸水多以大陆盐化咸水为主。

摘 要：
The spatial distribution and hydro-chemical characteristics of shallow groundwater in north of Shandong Province were systematically analyzed using Piper software,ion ratio coefficient and mathematical statistics.The results showed that:Hydro-chemical types of shallow groundwater were complex and changeable,which varied gradually from the freshwater to brackish water,salt water and brine from inland to coast.Variation coefficient of Cl-was the maximum,followed by Na+,and variation coefficient of HCO-3was the minimum among conventional inorganic ion compositions.MostγNa/γCl changed from 0.8to 0.9in coastal area whileγNa/γCl was generally more than 1.0in inland area.Besides,γNa/γCl was lower than 0.5in the local dot districts in inland area with saltwater/saline water type of Cl·SO4-Na or Cl·SO4-Na·Mg.The shallow salt water mainly derived from marine salinization in coastal areas while the shallow salt water salt water mainly derived from continental salinization in inland areas.
