摘　　要：通过音频大地电磁法在莱州湾地区海水动态监测勘查中的应用成果,结合原有资料的综合研究,对研究区海水入侵现状,有了进一步的认识,并对咸淡水界面进行了详细的划分,取得了良好的环境地质效果。表明EH-4连续电导率成像系统在圈定海水侵染通道,确定咸、淡水界面及监测界面运移规律监测工作中的有效性。Through a comprehensive study of the results of dynamic monitoring exploration for seawater in Laizhou Bay by AMT method and other original data,the authors acquired further understanding of the present situation of seawater invasion inside the study-area.Moreover,the authors divided the interface zones between the salt and the fresh water,which resulted in favorable effects of environmental geology.The results indicate that the AMT（EH-4） method is effective in determining the interfaces between the salt and the fresh water,delineating the infection tunnel of seawater and observing the regularity of interface migration.
