With the implementation of holistic tourism, the connotations and extension of tourism land are constantly expanding. The comprehensiveness, complexity, multi-profitability, and superposition of the spatial distribution of tourism land are continuously increasing, and the traditional concept and classification of the land used for tourism faces severe challenges. This study:1) Analyzed the current concepts and classifications of tourist land and discussed their disadvantages:The concept of tourism land is unclear, and its classification is fragmented and places too much emphasis on function; a space-time structure for the system is lacking. It is difficult to coordinate tourism land planning with other planning, and the sustainable utilization of resources and regional integration are impeded.2) Analyzed the spatial and temporal structured of the social ecosystem of tourism land, and studied the concept and classification of tourist land. Based on the concept of the social ecosystem, the concept and classification of tourism land in the context of holistic tourism are defined and classified. Tourism land was defined as a first-level land use type, under which land resources systems, the land for the user's system, basal correlation, and related land etc. four second-level land use types are defined. And land resource management strategies etc. third-level land use types and physiographic landscapes etc. 53 level four classes, are given. 3) Finally, the study discusses the concept and classification of to urism land in the context of regional tourism. It is accepted that the concept and classification of tourism land from a social ecosystem perspective attaches great importance to system level, structure, function, evolution, and interconnectivity, and is conductive to the construction of different space-time stages of tourism land use types and land use structures. This promotes the standardization, classification, management, temporal and dynamic prediction, and guidance of tourism land. The results of the study encompass ecological functions and social benefits of tourism land, and could facilitate improving the quality and comprehensive benefits of tourism land. The study covers core scenic spots as well as peripheral elements and could thus contribute to solving the contradiction between the use of scenic spots and communities, promoting the development of regional tourism and regional sustainable development.
