To improve land use efficiency,optimize urban spatial structure,and address management bottlenecks in land-constrained cities'stock industrial zones-such as the need for more refined flexible standards,inadequate land supply policies,and underdeveloped regulatory mechanisms-this paper summarizes the theoretical foundations and policy evolution of land use control in detailed planning,and takes the compilation and management of the territorial spatial detailed planning of Suzhou Xiangcheng Economic and Technological Development Zone as an empirical study to optimize the full-cycle path of"plan compilation-land use control-project implementation".The results show that:(1)Aligning with control demands,constructing a land use control approach that combines top-down and bottom-up mechanisms featuring"independent renewal+integrated planning and management"is the prerequisite for achieving mixed land use compatibility.(2)Clarifying control standards and formulating a land use control strategy of"rigidity-flexibility combination-positive-negative list system-coordination and tracking"serves as the guarantee for the implementation of industrial renewal.With"bottom-line control+flexible adaptation"as the core logic,rigid bottom lines lock in safety and public welfare,while the positive-negative list system releases space for mixed land use compatibility by clearly defining encouraged/compatible and prohibited functional types and applicable scenarios.(3)Adapting to control trends,future renewal of stock areas requires refined control covering the entire project cycle,clarifying the power boundaries of managers,and formulating targeted policies to enhance the operability of control rules and the coordination of overall planning processes.
