| 摘 要： | 通过对秦皇岛洋河-戴河冲积平原地区枣园水源地野外调查和不同水样的水文地球化学及多种同位素测试分析发现:1)该区海水入侵过程中的水化学作用主要是海水与粘土含量高的地层中钙质矿物阳离子的交换;2)海水入侵不是沿含水层整体向前推移,而是存在优先入侵通道(如断层和水势差较大水流方向)和局部入侵速度较快的现象;3)深层和浅层地下水水力联系较大,海水入侵已经影响到深层地下水;4)研究区地下水平均氚浓度为9.86 TU,地下水平均年龄介于17.6a～23.7 a之间,地下水流速约为2.11 m/a,整体上地下水循环路径短,径流速度快,地下水交替强烈.这些结果可为以后进一步治理海水入侵和合理利用地下水提供依据. |

| Abstract: | Through the field investigation and water sample test and hydrochemical and multi-isotopic measurement in Zaoyuan well field of Qinhuangdao,it can be found that the main hydrogeochemical behavior is cation exchange reaction between sodium and calcium-riched materials in high clay content sediments during the seawater intruding the fresh aquifer.In this study area,the seawater intursion is not entirely moving towards inland with parallel patterns.There are preferential intrusion channels,which result in the ... |
