| 摘 要： | 在水文地质调查和样品分析的基础上,应用水化学统计、离子相关性分析等方法对偃师市浅层地下水流动系统特征和水化学特征进行分析.研究表明:偃师市地下水化学特征具有明显的水平分带性,在沿着补给—径流—排泄的方向上,地下水化学类型由SO4·Cl-Na型水向HCO3-Ca·Mg、HCO3·SO4-Ca·Mg型水演化.总体上研究区地下水中TDS不高,均值为515.29 mg/L,与Mg2+、Ca2+、SO42-、Cl-质量浓度的分布规律具有明显的正相关性,主要表现为平原地区浓度高于南北两侧的丘陵山地.图3,表1,参15.

| Abstract: | On the basis of hydrogeological investigations and sample analysis, statistical methods and Ion correlation analysis were systematically used to study Groundwater flow system characteristics and the hydrochemical types of ground waters in Yanshi city. The results showed as follows： from the recharge ar- ea to the discharge area of Yanshi groundwater, the chemical characteristics of local groundwater had the obvious zonation patterns. The chemical type of groundwater changed from SO4 ~ C1 - Na to HCO3 - Ca ~ Mg and HCO3 ~ SOn - Ca ~ Mg. On the whole, the concentration of TDS in the groundwater of this region was moderate with an average value of 515.29 mg/L, and was in significantly positive correlation with the contents of Mg2＋ ,Ca2＋ ,SO42- ,C1-. The concentration of TDS in plains was obviously higher than that in both sides of the hills. 3figs. ,1tab. ,15refs. |
