摘　　要：为了解大武水源地地下水水化学特征及水质现状,选取2017年12月采集的57件水样,综合运用数理统计、相关性分析、Piper三线图、Gibbs模型和离子比法,分析了大武水源地的主要离子特征及其成因,并运用综合评价法对水源地水质进行评价。结果表明:大武水源地地下水主要阳离子为Ca 2+和Na+,约占阳离子总量的82.8%;主要阴离子为HCO 3-、SO 42-、Cl-,约占阴离子总量的91.9%;水化学类型以HCO 3·SO 4-Ca·Mg(Ca)型、HCO 3·SO 4·Cl-Ca·Mg(Ca)型、HCO 3·Cl-Ca·Mg(Ca)型为主;水化学组分主要受碳酸盐岩风化溶解控制;地下水水质都在Ⅲ类水以上,Ⅲ类水占据总水样的47.4%,Ⅳ类和Ⅴ类水占据了52.6%。研究成果对了解大武水源地水环境现状具有重要意义。The hydrochemical characteristics and water quality status of karst confined water in Dawu water source of Shandong Province were investigated using mathematical statistics,correlation analysis,Piper’s plot,Gibbs model and ion ratio method by analyzing 57 groundwater samples taken in 2017.The major ion characteristics and causes were examined,and the water quality was assessed by comprehensive evaluation method.Results reveal that Ca 2+and Na+are the major cations of groundwater,accounting for 82.8%of the total cations;HCO 3-,SO 42-,and Cl-are the main anions,accounting for 91.9%of the total anions.HCO 3·SO 4-Ca·Mg(Ca),HCO 3·SO 4·Cl-Ca·Mg(Ca),and HCO 3·Cl-Ca·Mg(Ca)are dominant hydrochemical patterns.The hydrochemical components are mainly controlled by weathering and dissolution of carbonate rock.The groundwater quality is above classⅢ,which accounts for 47.4%of the total water samples,whileⅣandⅤclasses occupy 52.6%of the total water samples.
