Adjustment and optimization of provincial major function oriented zone based on "Double Evaluation"

As a unique spatial governance mechanism in China, the Major Function Oriented Zone (MFOZ) plays a crucial role in coordinating territorial space development and protection. However, it reveals limitations in effectively supporting the new development paradigm under the evolving requirements of regional coordination and high-quality development. To enhance the systematic integration of MFOZ planning into the territorial spatial planning system, this study conducts an in-depth analysis of its functional orientation, policy framework, and spatial governance logic. Through clarifying the theoretical connections between "Double Evaluation" and MFOZ, we establish an evaluation system encompassing three core dimensions: ecological services, agricultural production, and urban development. The proposed methodology integrates dominant factor identification with adaptive refinement to formulate spatial adjustment strategies. By synthesizing natural resource endowments and socioeconomic development factors, this research develops an optimized technical framework for MFOZ delineation. Taking Guangdong province as a case study, we implement functional index evaluation and propose spatially differentiated adjustment schemes based on regional characteristics. The findings provide theoretical and practical references for MFOZ optimization in regional spatial planning systems.
