The invention discloses a dike safety monitoring method based on an active field source. The dike safety monitoring method comprises the steps that 1, a measuring line unit is arranged from the upstream side of a dike to the downstream side of the dike; 2, the measuring electrodes in the measuring line units are sequentially buried in the surface layer of the shallow ground from the head end to the tail end of the dike according to the set spacing distance; 3, the power supply positive electrode sequentially supplies power to the measuring electrodes in the measuring line units on the upstream side of the dike, current data of the measuring electrodes are collected at the same time, and voltage data of other non-power-supply measuring electrodes and voltage data of all the measuring electrodes in the other measuring line units are collected at the same time; 4, performing Fourier transform on the acquired current data and voltage time sequence data, extracting current and voltage data corresponding to the cor
