| 摘要: |
| 滨海含水层海水入侵的研究对于海水入侵的灾害防治及地下水资源的可持续管理具有重要的意义。基于国内外海水入侵影响因素研究现状，归纳了地质条件（包括海岸边界坡度、含水层介质分层、水力传导系数和弥散度）和水动力条件（包括海平面和地下水位的变化）这两类基础的影响因素，分析、总结了滨海含水层海水入侵机理，同时指出将相互作用、互有联系的影响因素作为一个系统开展研究，会更有利于理解海水入侵整个过程。 |

| Abstract: |
| The study of seawater intrusion in coastal aquifers is of great significance for the prevention and control of seawater intrusion and the sustainable management of groundwater resources. Based on the research status of the influencing factors of seawater intrusion at home and abroad, this paper summarizes the geological conditions (including coastal boundary slope, aquifer media stratification, hydraulic conductivity, and dispersion) and hydrodynamic conditions (including changes in sea level and groundwater level). Based on the dominant influencing factors of seawater intrusion, the mechanism of seawater intrusion in the coastal aquifer is analyzed and summarized. Moreover, it is pointed out that it will be more conducive to understand the whole process of seawater intrusion by studying the influencing factors of interaction and interrelation as a system. |
