摘要
在综合有关文献的基础上,分析了国内外海水入侵的研究现状,讨论了海水入侵的概念,认为海水入侵概念的核心是人为超量开采地下淡水造成海水与淡水的水动力平衡破坏;进行了海水入侵的影响因素和成因分析,指出发生海水入侵必须具备一定的水动力条件和水文地质条件;介绍了海水入侵的判别指标和三维动态监测方法,给出了海水入侵的防治措施,并提出了海水入侵有待加强研究的几个方面。
On the basis of synthesizing the papers relating to seawater intrusion at home and abroad,this paper analyzes the study status,discusses the concept of seawater intrusion and thinks that the essence of seawater intrusion is the imbalance of water pressure due to excessive groundwater pumping.In addition,this paper analyzes the cause of formation of seawater intrusion,and thinks that dynamic water condition and hydrogeological conditions are necessary for seawater intrusion.Finally,the identification index,three-dimensional survey methods,prevention and controlling measures,and further study trend for seawater intrusion are also put forward.
