In the light of simulation experiment, theoretical calculation and practical utilization, this paper deals emphatically with the application of magnetic method, electrical method and remote sensing technique to archaeological exploration, descrices its mechanism, means and effects, and proves the feasi-bility of applying geophysical prospecting to archaeological work. In view of the fact that geophysical archaeology is characterized by shallow depth and indistinction in physical properties, this paper also discusses the basic principles and methods for suppressing various interferences and raising resolution capability. Some preliminary views concerning the existent problems and the development trend of geophysical archaeology are also put forward for further discussion.
