摘要
水的环境同位素可以用来研究地下水的来源、地表水和地下水的关系,进而间接判断水质的相互影响.通过松花江吉林市江段两条剖面的氘、氚、氧同位素特征分析,结合水化学及水文地质条件,阐明了吉林市地下水来源以现代当地大气降水为主,仅在市区部分江段500m范围之内受松花江水影响,并计算了该段江水对地下水的补给比例.为判断当地突发性水污染事件对地下水的影响范围及污染防治提供了依据.
The water environmental isotopes can be used to study the source of groundwater and the relationship between surface and ground water,so that to indirectly judge the interaction of each other.By 18O,2H and 3H isotope analysis in Jilin section of Songhuajiang River,with chemical and hydrogeological conditions,it is concluded that the groundwater is mainly from atmospheric water,and is influenced by Songhuajiang River only around 500 m long in urban area.The supply ratio of river water to groundwater in this section is found out.It provides a basis for the control and prevention of water pollution incident.
