摘　　要：为掌握太子河流域平原区浅层地下水化学特征及水质状况,本文应用水化学成分分析法、相关性分析法、舒卡列夫分类法、Piper三线图解法、模糊综合评价法等方法,对该区域19眼浅层地下水监测井2018年水质监测数据进行分析。结果表明,研究区域浅层地下水化学类型以HCO3-Ca型、HCO3·Cl-Ca型、HCO3-Ca·Mg型为主,水质优于或达到Ⅲ类的监测井占比仅为31.6%,铁、锰指标超标现象较为普遍,部分监测井耗氧量、硝酸盐、氨氮等指标超标。In order to understand the chemical characteristics and water quality status of shallow groundwater in the plain area of the Taizi River basin,various methods including chemical component analysis,correlation analysis,Schoeller classification,Piper trilinear diagram,and fuzzy comprehensive evaluation are employed to analyze the 2018 water quality monitoring data from 19 shallow groundwater monitoring wells in the area.The results indicate that the dominant chemical types of shallow groundwater in the study area are HCO3-Ca,HCO3·Cl-Ca,and HCO3-Ca·Mg types.Only 31.6%of the monitoring wells achieve or exceed Class III water quality standards.Excessive levels of iron and manganese are common,and some monitoring wells showed exceedances in oxygen consumption,nitrate,and ammonia nitrogen levels.
