In this paper, the authors analyzed cases of applying EH-4 electromagnetic imaging system and 2D, 3D high density resistivity method to detecting seawater intrusion interfaces in Laizhou Bay area. The results show that the inversion profile of these methods provides rich and reliable geological information, which can help solve geological environment problem of this region, and these geophysical methods are effective and feasible in detecting seawater intrusion interfaces in Laizhou Bay area. Based on many profiles of EH-4 electromagnetic imaging system and high density resistivity method, the authors successfully figured out the distribution of the seawater intrusion interface, compiled the map of the seawater intrusion interface, and analyzed and sorted out electrical features of the region. These results has laid a solid foundation for the future geological survey in Laizhou Bay area.
