Seawater intrusion is one of the problems facing coastal countries and regions, and is also one of the major geological disasters in the Beibu Gulf economic zone. In this paper, based on systematic research on previous researches on Beibu Gulf region of Guangxi and using EH-4 audio magnetotelluric method int Beihai City, the authors made a preliminary study of the present situation of seawater intrusion, salty-fresh water dividing, and features of water-containing strata in the study area. It can be seen that, through the coastal city environmental geological survey work and by using reasonable geophysical detection methods and taking the preventive measures, the problem of seawater intrusion in coastal areas can be solved effectively. The authors' work has also confirmed that the EH-4 audio magnetotelluric method has a good effect in the investigation of seawater intrusion in the research area, and hence deserves wide application.
