摘要
本文通过对豫北平原多年的地下水开发利用及浅层地下水水化学资料分析,发现原为咸水-微咸水的大部分地区浅层地下水已淡化,咸水-微咸水分布区已由大面积分布演变为孤岛状,淡水资源量大幅增加。浅层地下水水化学现状、地下水14C同位素、地下水动力场也提供了浅层地下水淡化的证据。
By analyzing data of groundwater exploitation of many years and chemical analyses of shallow groundwater in the Northern Henan Plain, it is found that most of original saline-brackish shallow groundwater has been freshened. The distribution of saline-brackish groundwater has changed from a big area into arc-island type. As a result, the fresh water resources increase greatly. The chemical compositions, ^14C isotope of the groundwater and the dynamic field of the shallow aquifer also provide evidence for the freshening of the groundwater.
