摘要
通过水文地质调查、水样采集,结合地下水流动系统、吉布斯图、Piper三线图,对程家营盆地地下水水化学特征进行研究;结果表明,该区地下水呈弱碱性,水质较好,TDS、COD浓度较低,水化学类型为HCO3-Ca;F-、Mg2+主要受物质来源和山泉水影响;受水-岩相互作用影响,地下水Na+、Cl-、HCO3-沿地下水径流方向逐渐升高;SO24-、K+表现出沿地下水径流方向逐渐降低趋势;河流沿岸阶地区域地下水径流速度慢、水位埋深浅,受蒸发浓缩作用影响较强形成高TDS地下水;Ca2+离子随受水温和SO2-4离子浓度升高而降低。程家营盆地地下水水化学特征研究成果,对该区地下水资源的管理、保护以及可持续开发具有重要意义。
The hydrochemical characteristics of groundwater in Chengjiaying Basin are studied by hydrogeological investigation,water sample collection,combined with groundwater flow system,Gibbs diagram and Piper diagram,the results show that the groundwater in this area is weakly alkaline,the water quality is good,the concentration of TDS,COD is low,and the hydrochemical type is HCO3-Ca;F-,Mg2+is mainly affected by material source and mountain spring water.Under the influence of water-rock interaction,groundwater Na and Cl-,HCO3-increased gradually along the direction of groundwater runoff;SO24-,K showed a decreasing trend along the direction of groundwater runoff;the groundwater runoff rate along the terrace area along the river was slow,the water level was shallow,and the high TDS groundwater was strongly formed under the influence of evaporation concentration.Ca 2+ions decreased with the increase of water temperature and SO42-ion concentration.The research results of groundwater hydrochemical characteristics in Chengjiaying Basin are of great significance to the management,protection and sustainable development of groundwater resources in this area.
