摘要
本文中笔者利用双龙河剖面采集的D、18O同位素分析曹妃甸地区不同水体间的相互关系,识别区域水循环特征。研究发现区内河水、潜水和承压水均起源于大气降水,三者之间存在密切的水力联系;在三个区段上地下水具有不同的补径排条件;区内地下水循环系统可以划分为浅、中、深三级循环系统。
In order to study the hydrologic cycle character in the Caofeidan area, D and '80 isotope were collected along Shuanglong river profile to analysis the relationships of different water. Research found the river water, phreatic water and confined water are originated from atmospheric precipitation, and there is a close hydraulic connection among the three kinds of water. Recharge, runoff and discharge conditions are different at three seetions. Groundwater circulation system can be divided into shallow cycle system, middle cycle system and deep cycle system.
