基于空间一致性的城乡建设用地空间管制评价

Evaluation of Construction Land Space Control Based on Spatial Consistency

为科学合理测度土地利用总体规划对城乡建设用地的空间管制成效,从规划空间布局控制程度、空间扩张异向性以及空间形态控制效果3个维度构建评估框架,基于ArcGIS空间分析与指数模型,对崇左市中心城区进行实证研究。结果表明:基于空间一致性的多维度评估框架体系能较好地评估土地规划对城乡建设用地的管制成效,可为完善规划评估方法,促进新时代国土空间规划编制和实施提供参考;城乡建设用地规模控制与空间管制成效相差较大;崇左市中心城区东面扩张强度和速度均处于较高水平,城乡建设用地发展重心向东发生偏移,但仍在符合规划的范围内。

In order to scientifically and reasonably measure the spatial control effectiveness of general land use planning on urban and rural construction land,an evaluation framework was constructed from three dimensions of planning spatial layout control degree,spatial expansion anisotropy and spatial form control effect.Based on ArcGIS spatial analysis and index model,an empirical study was conducted on the central urban area of Chongzuo City.The results showed that:The multi-dimensional evaluation framework system based on spatial consistency can better evaluate the control effect of land planning on urban and rural construction land.In addition,this framework can provide reference for improving the planning evaluation method and promoting the compilation and implementation of national territory spatial planning in the new era.The scale of urban and rural construction land control and space control effect is greatly different.The eastern expansion intensity and speed of Chongzuo’s central urban area are both at a high level.Although the center of urban and rural construction land development shifts eastward,it is still in line with the planning.
