摘要

摘要: 地下水监测及数理分析是地下水动态研究的主要方法。但目前海岸带地区多以陆域地下水监测为主,海域部分尤其具有多层含水层系统的海底地下水缺少直接监测数据。本研究通过海域钻孔ZK03与ZK08实时监测不同层位海底地下水动态以及海洋潮汐变化,结合其地层结构和沉积演化背景,分析莱州湾海底地下水动态特征并揭示其影响机制。研究结果表明,莱州湾海底地下水动态具有周期性和分层性特征;全新世含水层与海水关系密切,其海水入侵界面垂向上厚10 m左右。海底地下水分层与沉积地层划分大致相同,其动态特征是在地层结构及沉积演化环境影响下,降水、径流及潮汐驱动不同层深地下水间或地下水与海水间混合作用的结果。本文初步构建了海底地下水分布模式,探讨区域地下水与海水的相互作用关系。莱州湾海底地下水动态研究对于深入分析海(咸)水界面变化机制及探索海底地下水排泄具有推动作用。

Abstract: Groundwater monitoring combined with mathematical analysis is the main method of groundwater dynamics studies. But there is less monitoring data for submarine groundwater than inland groundwater in the most coastal areas. In this study, sea drillings ZK03, ZK08 were designed to real-time monitor dynamics characteristic of submarine groundwater in multi-layers aquifers and ocean tides. Combined with stratum structure and sedimentary evolution setting, the paper analyzed the dynamic characteristics of submarine groundwater in the Laizhou Bay and revealed the driving mechanism. The results showed that submarine groundwater dynamic appeared to be periodic and stratified in the Laizhou Bay, Holocene aquifer were closely associated with the sea, where the vertical thickness of seawater intrusion interface was about 10 m. Submarine groundwater stratification were roughly consistent with sedimentary strata. Controlled by strata structure and sedimentary environment, the mixing process in different aquifer groundwater or between groundwater and seawater drived by precipitation, groundwater runoff and tide was the main driving mechanism of submarine groundwater dynamic. Then the paper constructed a preliminary submarine groundwater distribution pattern to explore the interaction between groundwater and seawater. The study on the dynamics characteristic of submarine groundwater in the Laizhou Bay play a positive role in analyzing saltwater interface change mechanism and exploring the submarine groundwater discharge.
