Abstract: The regulatory behavior norms for land reclamation are not only the basic normative guidance for deepening rural land system reform under the dimension of comprehensive promotion of rural revitalization, but also the necessary institutional carrier for confirming and reflecting on the community level of "environmental governance" behavior related to "natural resource supervision" involved in land governance behavior in this micro field. Based on the theoretical paradigm of "collaborative governance", an attempt can be made to construct a cooperative model in the field of land reclamation supervision that is more in line with the modernization of Chinese style agriculture and rural areas. The practice field of collaborative governance of land reclamation regulatory behavior mainly involves goal orientation and hindrance, which provide feasibility proof for the introduction of collaborative governance theory and can be called the "feasible essence" of collaborative governance of land reclamation regulatory behavior. The stakeholders in the collaborative governance of land reclamation regulatory behavior mainly involve subject structure and participation quality, which provide a practical basis for the implementation of collaborative governance theory and can be called the "practical essence" of collaborative governance of land reclamation regulatory behavior. The willingness to cooperate in collaborative governance of land reclamation regulatory behavior mainly involves interest orientation and inspection carrier. It provides institutionalized suggestions for the application of collaborative governance theory and can be called the "expected essence" of collaborative governance of land reclamation regulatory behavior.
