摘要:

在阅海湖西岸建立了一条原位监测剖面,通过分析湖水与地下水的动态规律、动态相关性以及氘、氧同位素分布特征,解析阅海湖与地下水之间的转化关系和驱动力条件。结果表明:①阅海湖仅与近岸区浅层地下水之间存在密切的动态响应关系;②在近岸区,湖水补给地下水的作用过程在5 m深度范围内明显,当地下水埋深大于5 m时,湖水向地下水的转化补给作用减弱;③人工补水形成的高水头是驱动湖水向近岸区浅层地下水转化的直接动力因素。

Abstract: An in-situ monitoring profile was built on the west bank of the Yuehai Lake. The conversion between lake water of the Yuehai Lake and groundwater and its driving conditions were explored by analyzing the dynamics and the dynamic correlation between lake water and groundwater as well as the distribution of deuterium and oxygen isotopes. The results indicated that: ①There was the close dynamic responses between the Yuehai Lake and the shallow groundwater only in the near-shore area; ② In the near-shore area, lake water recharged groundwater obviously within 5-m depth, but its recharge to groundwater deeper than 5 m decreased; ③ High water head resulted from artificial water compensation was the direct driving factor of the conversion from lake water to shallow groundwater in the near-shore area.
