采用稳定同位素--18O、D,结合常规离子分析结果确定了莱州湾东岸海底地下水的来源,并采用数值方法估算了其量值。结果表明：莱州湾东岸海底地下水主要来源于波浪、潮汐的海水补给,同时在一定程度上受地下水径流排泄的影响,三者对海底地下水的贡献率分别为31.0%,56.3%和12.7%。研究结果对于合理开发、科学保护海底地下水具有重要现实意义。

Submarine groundwater discharge(SGD)is the important pathway for the study of Land-Ocean interac-tions, while source identification is the premise for rational utilization of submarine groundwater resources. In this paper, attempts were made to identify the source of submarine groundwater along the east coast of the Laizhou Bay by using stable isotopes-18O and D, combined with conventional ions analysis. The quantity estimation was made using numerical methods. The results show that wave action and tidal fluctuation are the main sources influencing SGD. Moreover, the land groundwater discharge, also has certain effect on it. Contributions of, wave run-up, tidal fluctuation and groundwater runoff to groundwater are 12.7%, 31.0% and 56.3%, respectively. These results are very helpful to the rational development and scientific protection of submarine groundwater.
