Abstract：

China’s metropolitan areas are characterized by high population density and complex interlacing of urban and natural landscapes, leading to prominent conflicts and insufficient coordination among Production-Living-Ecological Spaces. Based on the “Precise Adaptation” regional planning concept, this paper builds a multi-scenario target-driven, multi-rule system constrained spatial optimization model, and proposes a spatial optimization scheme with diversity and variability under different scenarios. Taking Beijing Capital Metropolitan Area as a case study, the research conducts indicator measurement and model derivation at the subdistrict/township level, exploring a synergistic derivation method from macro-planning to local optimization. The analytical results validate the effectiveness of this spatial optimization strategy in enhancing the resilience and functional efficiency of metropolitan areas, providing a scientific approach to improve regional ecological and economic benefits. This methodology also breaks through traditional land-use range derivation techniques, offering a quantitative analytical tool for optimizing spatial structures in regional planning.
