Presented is an electric field intensity compensation method for constructing a non-uniform electric field through an auxiliary electrode, including steps of: in a matrix electrode unit, designing an auxiliary electrode arrangement position according to the spatial distribution of the pollutant concentration; designing the polarity of the auxiliary electrode according to the position relationship between the auxiliary electrode and matrix electrodes; and constructing a non-uniform electric field by the auxiliary electrode and the matrix electrodes to implement space compensation of the electric field intensity. In the present invention, a non-uniform electric field matching a pollutant concentration field is constructed by setting the space arrangement and polarity of the auxiliary electrodes on the basis of the matrix electrodes according to the spatial distribution of the pollutant concentration, the contradiction of consistency between the heterogeneity of the spatial distribution of the pollutants and the removal efficiency of the uniform electric field is solved, and the spatial difference of efficiency of electrokinetically remedying organic contaminated soil is avoided, thereby improving the overall space remediation efficiency of electrokinetic remediation.
