The invention discloses a moving structure of an ecological floating island through magnetic force, and solves the problem that in the prior art, operations of artificial gather management and the like on the ecological floating island need to be completed on the water, so that the efficiency is low. A method for moving an ecological floating island in the lake through magnetic force disclosed bythe invention comprises the following steps: step I: acquainting the position information of a movable FRID label and a fixed FRID label through an FRID reader in a real-time manner, and through a unmanned aerial vehicle controller, controlling an unmanned aerial vehicle to move to the position of the fixed FRID label; step II: starting an electromagnet controller, controlling an electromagnet towork, after the electromagnet works, generating magnetic force, and enabling the electromagnet and a magnet to be mutually attracted so as to be connected integrally; and step III: through a connecting line accommodating machine, pulling a connecting line, and further moving a floating island body to the shore. According to the method disclosed by the invention, the conservation time can be greatly shortened, the risk of operations in the river can be avoided, and the safety can be improved.
