To study the hydrochemical characteristics of groundwater and the factors controlling the alluvial-proluvial fan of the Qinhe River, 60 samples were collected including 9 surface water samples and 51 groundwater samples. The distribution characteristics of the hydrochemistry and major controlling factors of hydrochemical evolution processes of surface water and groundwater in the study area were analyzed by using mathematical statistics, the Schakerev classification, Piper diagrams, Schoeller diagrams, Gibbs plots, and ion ratios. The results show that:① the major anions and cations of surface water and groundwater in the study area are Ca, Mg, SO, and HCO. The recharge sources of surface water and groundwater are closely related; ② the major hydrochemical types of the groundwater are HCO-Ca, HCO-Ca·Mg, and HCO·SO-Ca·Mg, while the major hydrochemical type of surface water is HCO·SO-Ca·Mg; and ③ the major ions of surface water and groundwater are affected by carbonate mineral weathering and dissolution, ion exchange, and evaporation. Sulfuric acid and carbonic acid were involved in carbonate mineral weathering and dissolution.
为研究沁河冲洪积扇区地下水水化学特征及其控制因素，采集了60个样品，其中包括9个地表水样品和51个地下水样品。运用数理统计、舒卡列夫分类法、皮帕尔图、舍勒图、吉布斯图和离子比值等方法，分析了研究区地表水和地下水水化学分布特征及水化学演化过程的主要控制因素。结果表明：①研究区地表水和地下水的主要阴、阳离子为Ca、Mg、SO和HCO，地表水与地下水的补给来源密切相关；②地下水主要水化学类型为HCO-Ca、HCO-Ca·Mg和HCO·SO-Ca·Mg，地表水主要水化学类型为HCO·SO-Ca·Mg；③地表水和地下水的主要离子受碳酸盐矿物风化溶解、离子交换及蒸发作用影响，硫酸和碳酸参与了碳酸盐矿物的风化溶解过程。
