摘　　要：在全面的水质调查的基础上,对苏锡常地区采集潜水水样进行分析。测试结果表明:苏锡常地区潜水水质在空间分布上具有较为明显的分带性。通过分析认为:苏锡常地区潜水的水质在空间上的差异与含水层及其包气带的沉积环境有着密切的联系;基底构造的继承性差异沉降运动、气候冷暖交替引起的海面频繁升降以及河流、湖泊的搬运与沉积均对区内潜水水质的水化学特征的形成起到控制性作用。Based on an overall investigation of water quality, the authors analyzed the phreatic water samples collected in the study area. The testing results demonstrated that the phreatic water quality was of evident zoning characteristics in spatial distribution. The analyses further showed the difference of phreatic water quality in spatial distribution was of close relationship with the sedimentary environment of aquifer and its vadose; inherited differential subsidence movement of basement structure, frequent ascending and descending of sea level aroused by climate alternation, transportation and sedimentation of rivers and lakes played a controlling role to the formation of hydrochemical properties of phreatic water quality.
