摘　　要：为提升上海市地下水环境质量,探讨了上海市经济快速发展时期(2001—2013年)全市潜水含水层及第Ⅱ~Ⅴ承压含水层地下水矿化度与Na^+,Ca^(2+),Mg^(2+),Cl^-,SO_4^(2-),HCO_3^-,NO_3^-,NO_2^-,NH_4^+,TFe,Mn^(2+)浓度之间的耦合关系,发现各含水层地下水矿化度与不同离子浓度的空间分布之间具有一定规律性,不同含水层矿化度与不同种类离子浓度之间存在显著正相关或者负相关.鉴于矿化度与各水化学离子之间的相互关系在一定程度上反映了地下水的成因,因此,矿化度是反映地下水环境质量演化趋势的优良指标之一.Based on the relevant data of 2001--2013 （the period of fast economic development） of Shanghai city, this study probed into the coupling relationship between the mineralization degree of the phreatic aquifer, the second, the third, the forth and the fifth confined aquifer, and the regular hydrochemistryion（such as Na＋, Ca2＋, Mg2＋, Cl , SO24-, HCO3-, NO3-, NO2-, NH4＋, TFe, Mn2＋） concentration, so as to improve the quality of groundwater environment in Shanghai city. The results show there is regularity between the groundwater mineralization degree of each aquifer and the spatial distribution of the concentration of different ion. There is obvious positive and negative correlation between the mineralization degree of different confined aquifers and the concentration of different ion. Considering the fact that the relationship between the mineralization degree and each hydrochemistry ion reflects the cause of groundwater to a degree, the mineralization degree is one of the good indices in revealing the evolutionary trend of groundwater environmental quality.
