China has entered a New Era of spatial governance that leads the country's "multiple planning integration" with the territorial spatial planning. It has stricter control and higher requirements in technology and coherence over each specialty planning. Consequently, the paper reexamines the nature and status of tourism planning in the New Era of territorial spatial planning, and based on the characteristics of industrial specialization and spatial integration in tourism planning, it divides tourism planning into four types: strategy planning, coordination planning, development planning and construction planning. Then, taking the tourism development planning as an example, the paper puts forward six major transformations of tourism planning: from unbounded thought to bounded, integrated and spatial thought in planning concept; from the will of Party A to market orientation in planning ideas; from "large and all-inclusive" to "specialized and refined" in planning content; from conceptual logic to spatial logic in technical route; from closed to open in planning mode and from lack of technology to technical integration in tourism planning, in order to promote tourism planning to integrate into the territorial spatial planning system in the New Era, and further take lead in the transformation, upgrading and high-quality development of China's tourism industry.
