The rule of the“Three—Rights separation”of rural land means that the realization of the specific mode of rural land transfer must be divided into rural land management rights.If there is no right division，there will be no rural land management right.Its essence is to overcome the legal obstacles of farmland circulation through the innovation of legal and technical tools.Legislation serves the practical needs of rural land transfer，and intentionally dilutes the nature of Rural land management right.In the interpretation，it is necessary to consider both the transfer period and the transfer mode to make it clear.The key and core of understanding the land management right is to clarify its formation mechanism，which needs to be grasped in the unity of opposites between land circulation and right separation.In the context of“Three—Rights separation”of rural land，the word“circulation”in legislation has a specific legal meaning.The socalled“circulation land management right”under the situation of the need for the separation of rights should be interpreted as the formation of the Rural land management right；the socalled“circulation land management right”and“the re circulation land management right”under the situation of no need of the right separation as the circulation of rural land management right，so as to realize the standardization and unification of the legal meaning of the word circulation.The legal structure should be unified on the basis of systematic interpretation，and eliminate the difficulties of understanding and application caused by the diversity of land management rights and its existing forms.
