在分析研究区浅层地下水空间分布特征的基础上,采用同位素与化学分析相结合的方法研究苏锡常浅层地下水的补径排条件.利用氢氧同位素的分析结果,建立潜水与微承压水的δD-δ180关系曲线,分析潜水含水层与河流、湖泊等地表水体关系以及微承水的蒸发程度;利用放射性同位素氚与14C研究微承水与现代水的补给关系;利用常规的水化学分析方法研究浅层地下水补给源的变化问题.结合研究区地下水水位、地层岩性、地形、地貌等多方面因素综合分析了浅层地下水的补径排条件,从而指导苏锡常地区浅层地下水合理开发利用.%According to the spatial distribution characteristics of shallow groundwater in Suzhou-Wuxi-Changzhou area, replenishment, runoff and discharge conditions of the shallow groundwater were studied by isotope and hydrochemishtry analysis. The δD-δ18O％ curve was established for phreatic and micro-confined groundwater based on the analyzed results of hydrogen and oxygen isotope, so as analyze the relation between the phreatic aquifer and surface water body, and the evaporation degree of micro-confined groundwater. The replenishment relation between micro-confined groundwater and current water was studied with radioisotope tritium and 14C. The replenishment source change of the shallow groundwater was studied with the conventional method of chemical analysis.
