Exploring the establishment of the classification system under the new institutional arrangements for resource management is important for the integrated management of natural resources. This study analyzed the existing natural resource theories, jurisprudence, and management classifications, which cannot well avoid the overlap of natural resource management and the classification standards are not uniform, which is not conducive to producing a clear inventory of natural resources. It further analyzed the basic connotation of integrated management of natural resources by combining natural resource element management and integrated management, hierarchical management and classified management, and resource supervision and resource asset management. On this basis, the requirements for resource classification in connection with existing laws, effective integration with traditional classification, and integrated management of natural resources are discussed, and unified classification standards, effective connection between new and old classifications, and organic integration of academic, legal, and management classifications are proposed. Based on the classification principles, a natural resource classification system of 3 main categories, 15 sub-categories, and 53 types was constructed for the integrated management of natural resources.
