The invention discloses an electric control steering system, a control method and a land leveler in the technical field of electric control steering control, and aims to solve the technical problems of poor redundancy and poor safety. The electric control steering system comprises an electromagnetic valve steering gear and an electronic steering gear, the control redundancy of controlling the steering stroke of a steering oil cylinder is improved for a steering signal controller, a hydraulic steering pump and an electric steering pump are communicated in a one-hydraulic-one-electric mode, and an intermediate valve is communicated with one of the hydraulic steering pump and the electric steering pump to improve the power redundancy of the electric control steering system. According to the steering signal controller, the safety is improved by judging the pressure of an intermediate valve and selecting a steering pump, and the steering signal controller calculates the target steering angle. The mutual communication and signal connection of the electromagnetic valve steering gear, the electronic steering gear, the steering signal controller, the hydraulic steering pump, the electric steering pump and the intermediate valve are linked with the control relation, so that the safety and redundancy of controlling the steering stroke by using the steering control device are improved.
