Based on the effects of integrated remote-sensing and ground geophysicalprospecting information interpretation method in such aspects as trailing wa-ter-bearing fractural linear structures, delineating water-bearing structures at contact zone and searching for concealed water-healing structures overlain by volcanic jocks, this paper deals with the establishment of the Water-search-ing methodological series consisting of remote-sensing (aerophoto interpreta-tion)-ground geophysir.nl prospecting (resistivity method or extremely low frequency method, a-card method, IP decay field method, shallow seismic method etc.), and expounds the necessity, rationality and possibility of the adoption of this series. It is thus pointed out that the three-dimensionality and multivariation of the hydrogeophysical information has become an impor tant subject for hydrogeophysicists.
