The invention relates to an electric field dynamic regulating and controlling method based on soil electrical parameters. The electric field dynamic regulating and controlling method comprises the following steps that a concentration field of contaminants in organic contaminated soil is measured, and the electrode distributing position and polarity are determined; the size of input voltage is calculated according to contaminant concentration grading and the soil electrical parameters; and spatial distribution of an electric field is dynamically regulated and controlled based on changes of thesoil electrical parameters, and the matching degree between the electric field and the contaminant concentration field is kept. The electric field dynamic regulating and controlling method based on the soil electrical parameters effectively solves the problem of spatial difference of the electric repairing project efficiency of the organic contaminated soil, and improves the overall project repairefficiency of electric repairing.
