Abstract: As China's urbanizan on enters the era of re-development, the shift from single-purpose development to mixed-use development has become inevitable. The existing land use control system is ill-suited to the complexities of mixed land-use,lacking refined and effective control tools, dynamic feedback mechanisms in development process, and flexible planning and management procedures. In response to the imperative of lifecycle management of mixed-use development, this paper proposes a double-layered system that regulates both land uses and architectural functions. The proposed system includes unit and site layers, clarifying the roles and interfaces required for land use control at different stages of mixed-use land planning and construction management. It helps improve the forward transmission and reverse feedback mechanisms in land use regulation.
