以南水北调梁济运河通水前后的浅层地下水水化学要素为依据，采用派珀三线图解法、离子比例系数等方法，分析通水对浅层地下水化学成分的影响。结果表明：①通水前，滨湖区浅层地下水化学类型以Ca2＋－M g2＋－HCO3－型为主，黄泛平原区以Na＋＋K＋－Cl－－SO2－4型和Ca2＋－M g2＋－Cl－－SO2－4型为主。②与未通水期（2012年12月）相比，通水期（2013年12月）黄泛平原区浅层地下水流动速度加快，易溶盐的累积过程发生改变，由在90号－97号－99号方向上的递增改为递减。矿化度方面，通水期滨湖区地下水矿化度高于未通水期，通水期黄泛平原区地下水矿化度低于未通水期。③从地下水化学成分的年际变化来看：通水对滨湖区地下水化学成分的影响较小；通水期黄泛平原区浅层地下水中汇入矿化度低、含有大量 CO2的水，促进石灰岩组分分解并降低了地下水矿化度，致使 Na＋＋ K＋、Ca2＋、HCO3－浓度明显增加。

Based on hydro‐chemistry elements of shallow groundwater in the Liangji Canal Basin before and after South‐to‐North Wa‐ter Transfer Project in operation ,piper diagram ,the ions ratio coefficients and other methods are used to analyze the impact of water transfer on the chemical composition of shallow groundwater .The results show that :① before the completion of the project ,the type of Ca2+ -Mg2+ -HCO3- was major constituent in the Lake District's shallow groundwater ,while in the Yellow River Flooding Areas ,Na+ +K+ -Cl- - SO2 -4 and Ca2+ -Mg2+ -Cl- -SO2 -4 types were dominant .② Compared 2013‐12 with 2012‐12 ,the ve‐locity of shallow groundwater flow speeded up ,and the cumulative process of soluble salt started to diminish instead of increasing in the direction of 90# -97# -99# in the Yellow River Flooding Area .As for salinity ,the groundwater salinity of the Lake District in 2013‐12 was higher than that in 2012‐12 ,while the groundwater salinity of the Yellow River Flooding Area in 2013‐12 was lower than that in 2012‐12 .③ When the annual variation of chemical composition of groundwater is considered ,the influence of Water Transfer on the chemical composition of groundwater of the Lake District is weaker .Water contained low salinity and massive CO2 was injected into shallow groundwater of the Yellow River Flooding Area ,which has promoted the decomposition of limestone com‐ponent ,and resulted in a significant increase inNa + +K+ 、Ca2+ 、HCO3- .
