Summary:The invention discloses a polarization anomaly information extraction technology based on a resistivity inversion result, and the technology comprises the following steps: introducing a Cole-Cole model into controllable source one-dimensional forward modeling, and deducing to obtain a one-dimensional frequency domain forward modeling formula containing an induced polarization effect; simulating frequency domain electromagnetic field response under the condition of the layered induced polarization medium, and analyzing the influence condition of induced polarization parameters in the Cole-Cole model on the electromagnetic field response; a step-by-step processing strategy is adopted to carry out inversion processing on electrical parameters of the actually measured electromagnetic field data, and geoelectric section resistivity data is obtained; and extracting geoelectric section resistivity data by adopting mapping imaging and acute optimal layer transmission imaging to obtain induced polarization abnormal in
