摘要
根据南通地区地下水的水动力场,水温度场和水化学场的研究,提出了本区三个含水系统,研究了它们之间的水力联系和水化学形成特征及咸淡水的演化规律。地下水的环境同位素(~2H、’^(18)O、~3H、和^(14)C)研究确定了地下水循环过程及其形成相对年限,提出了咸水层中的淡水体及淡水层的咸化形成的几种机理,最后建立了研究区的区域地下水流系统概念模型。
Three aquifer systems were established in Nan- tong area on the basis of bharacteristics of waterdynamic, water temperature and chemical fields.The hydraulic conneetion between these systmse,the formation of hydrochemistry and evolutio-nal characteristics of salt-fresh groundwater are di-scusssed. Circulation cycle and relation age of grou-ndwater were determined on the basis of environme-ntal isotopes. Some mechanisms were povided for theformation of fresh body in salt aquifer and the sali-nization of fresh aquifer. Finally, a conception mo-del of groundwater was established in the studyarea.
