县级国土空间规划分区方法探索——以湖北省黄梅县为例

国土空间规划分区是在统一联动的国土空间分区管控体系中为弥补中微观尺度结构性管控作用缺失而提出的新的分区层级，其技术方法研究具有重大的理论和实践意义。在分析空间治理“精明化”“精准化”“精细化”要求、对比不同分区逻辑的空间分区方法的基础上，利用空间分析、多元统计、加权Voronoi图等技术方法，从主体功能“点轴”发展规律出发，研究构建了定性与定量相结合的分区方法，并以黄梅县为案例进行了实证研究。研究表明：本文方法能够有效划定符合《市级国土空间总体规划编制指南（试行）》中一级规划分区内涵的分区单元，弥补了规划分区方法的缺失；依托功能发展结构的“自上而下”分区逻辑有效将空间结构管控内涵融入规划分区，实现了对空间结构的引导和管控；通过加权Voronoi图模型，识别空间的最优功能导向，提高了规划分区的科学性、技术性。

Exploration on the method of county-level territorial planning zoning: A case study of Huangmei,Hubei

Planning zoning is a new zoning level proposed by the unified land and space zoning management and control system to make up for the lack of structural management and control at the meso-micro scale. The research on its technical methods is of great theoretical and practical significance. Based on the analysis of the requirements of "shrewdness", "accuracy" and "refinement" of spatial governance and the comparison of spatial zoning methods with different zoning logics, this paper studies and constructs a zoning method combining qualitative and quantitative methods from the development law of the main function "point axis" by using technical methods such as spatial analysis, multivariate statistics and weighted Voronoi diagram. In addition, this paper conducts an empirical study with Huangmei as a case. The research shows that: (1) The method in this paper can effectively delineate the zoning units in line with the connotation of primary planning zoning in the "Guidelines for the Compilation of Municipal Land and Space Master Plan (Trial)", which makes up for the lack of planning zoning methods. (2) Relying on the "top-down" zoning logic of functional development structure, the connotation of spatial structure management and control is effectively integrated into the planning zoning, realizing the guidance and management of spatial structure. (3) Through the weighted Voronoi diagram model, the optimal function orientation of space is identified, which improves the scientificity and technicality of planning zoning.
