The invention discloses an agricultural land navigation path planning system for an autonomous vehicle and a method thereof. The system comprises a farmland data collection assembly, a farmland construction division assembly, a basic path planning assembly, a land parcel division assembly and a farmland navigation path merging assembly. And the farmland data collection assembly collects farmland information by driving the vehicle to run around the outermost ridge of the farmland by one circle. The farmland structure dividing assembly divides a starting ridge, a stopping ridge, a far edge, a near edge, the number of ridges and the positions of steering anchor points of the farmland based on the average ridge width of the farmland, the positions of the steering anchor points and the turning radius of a vehicle. And the basic path planning assembly plans a continuous travel path of the vehicle in different basic land parcels in a manner of crossing at least one ridge land and excluding repeated travel in differe
