摘　　要：结合前人的研究成果和施工的钻孔资料,基本查明了黄河三角洲浅层地下水的分布和埋藏条件,分析了该区地下水和黄河水的氢氧同位素组分(18O、D和T).研究结果表明:(1)黄河三角洲地下浅层有潜水和承压水两个含水层,两者来自完全不同的水源;(2)潜水起源于黄河水和大气降水的入渗补给,与黄河的水力联系强,属于大气成因溶滤水;潜水水交替条件较好,平均停留时间约为5.30年;(3)承压水是海侵时侵入的海水和古大陆水混合后沉积下来的水,与黄河水的水力联系弱,属于沉积水.Based on the other researh achievements and the drilling of new boreholes, the knowledge of stratum and identify aquifers of the shallow part of the Yellow River delta （YRD） is obtained. Groundwater samples of the shallow part and water samples from the Yellow River were collected for ^18O, D and T analyses. The results are ,as the followings. Firstly, the groundwater in the shallow part of the YRD can be divided into phreatie water and confined water, which are so different to each other, Secondly,the Yellow River recharges directly the phreatic aquifer in which groundwater moves quickly, and the mean residence time is 5,30years. Thirdly, the groundwater kept in the confined aquifer is old marine deposit water mixed by old terrestrial groundwater. And the Yellow River water cannot reach the confined aquifer.
