Abstract: Territorial spatial planning is an important measure of space governance reform in China in the new era. It has prominent institutional and policy-oriented attributes, which should reflect the requirements of ecological civilization construction, land use control, effective transmission of planning and informational scientific governance. Based on the analysis of the background and dynamics of the relevant systems and policies of territorial spatial planning in China, this paper discusses the issues of territorial spatial planning, such as the depth of planning content, the elasticity of use-controlled conduction and the rationality of compilation methods. The study draws the following conclusions: the content depth of territorial spatial planning should emphasize the control of strictly protected space, the planning of the other special elements should reach the outline depth; in order to ensure effective transmission, it is necessary to increase the use zoning at the urban level in the space control conduction; the planning compilation method should strengthen the application of big data and geographic information technology in order to enhance its rationality.
