Over the past nearly 30 years,geophysical technical standards for geological surveys have successively experienced zero standards,sparse standards,and standard series.As a result,a series of standard systems of gravity,magnetic,electrical,seismic,and radioactive prospecting have been gradually established,which play an important role in establishing standardized work procedures and promoting new methods and techniques in the field of geophysical techniques for geological surveys in China.However,with the transformation and development of geological surveys in China,the current standard systems of geophysical prospecting are yet to meet the requirements of geological surveys at present.The paper summarizes the development status of geophysical standards for geological surveys in China and explores the research direction and development trend of the standardization of geophysical techniques according to the need for geophysical methods and technologies in the transformation and development of geological surveys in China.
