During the sixth five-year-plan period, especially since the opening to the world of 14 coastal ports as decided by the State Council in 1984, 1:50,000 re gional geophysical survey has been conducted for 38 large or medium-sized ci ties with the help of such traditional geophysical techniques as aeromagnetic survey, gravity survey and electrical sounding. The results provide data of esse ntial importance for basic geology, engineering geology as well as investigationof underground water and geothermal resources, showing remarkable social and economic benefit. For the purpose of adapting geophysical work to extensive and many-sided requirements of modern urban construction, the author proposes in this paper the substance, methods and procedure for a new round of urban geo physical prospecting, which include seismic intensity zoning, investigation of fault activity, layering and regionalization for rock-soil mechanics of ground, regional survey of bed rock, fracture water and concealed geothermal areas. The develop ment of a new round of urban regional geophysical prospecting in its substance, methods and procedure will undoubtedly raise the urban regional geophysical prospecting and its social and economic benefit to a new level.
