Abstract The geophysical inversion can be regarded as an understanding or interpretation of geophysical properties on the basis of the observed data, while the inversion of multiple geophysical data can be regarded as the fusion of multiple sensor data. In this paper the fuzzy features of geophysical data are analyzed. The characteristic data of different physical meanings and scales, and the knowledge of geology and geophysics in the studied area are combined using the method of a uniform linguistic defuzzification. The method integrates the geophysical expert knowledge, and carries out data fusion using the fuzzy inferential network. The method makes full use of all information of manifold geophysical data, avoiding the complicated calculation in linear joint inversion, and provides a new idea for the geophysical inversion about the data fusion point of view. It is proved to be effective through the modeling test and application to water exploration in the Guyuan area.
