Claim 1:
2. The method according to claim 1, wherein a process of carrying out data fusion on the extracted resistivity data at the same position by utilizing a principal component analysis method is as follows:
carrying out a data centralization, that is, standardizing resistivity data acquired in all prospecting modes;
solving a covariance matrix between standardized variables, and measuring whether deviation change trends of two variables are consistent or not;
solving characteristic values and characteristic vectors of covariance, arranging the characteristic values in an ascending order, selecting the largest characteristic value, and solving the characteristic vector corresponding to the largest characteristic value; and
projecting a sample point of the centralized data to a characteristic vector base with the maximum characteristic value to acquire a fused resistivity data result.
