Abstract: Under the rural revitalization strategy, in order to promote the standardized application of the financing guarantee system of land management rights, the legal disputes such as the guarantee mode of land management rights mortgage, the object of contractor's mortgage, and the realization mode of land management rights mortgage were interpreted from the perspective of legal theory. The guarantee mode of mortgage was proved theoretically,and it was clear that the object of mortgage financing by the contractor was the land management right. It was proposed that the disposal of land management rights needed to increase the trusteeship realization method, and supplement the realization mechanism of land management rights mortgage from legal and technical means.

Key words: land management right, mortgage, trusteeship
