中国主体功能区格局优化研究

Pattern Optimization of National Major Function-oriented Zones

主体功能区战略是中国国土空间治理重要的基础性制度创新,在新的国土空间规划体系下,亟需对主体功能区划格局进行调整优化。采用基本功能与叠加功能相融合的“3+N”主体功能分区体系,构建指标体系,采用条件组合法结合一票否决法进行综合评价等级划分。研究结果表明:(1)中国主体功能区格局优化调整后,农产品主产区增加24个区县,重点生态功能区增加51个区县,城市化地区减少75个区县。优化方案体现重视粮食安全、生态安全和城市集约高效发展的目标。(2)中国主体功能区格局优化调整后,重要城市化地区主体功能类型区呈现核心-边缘结构,即城市化地区、农产品主产区和重点生态功能区三者的比例关系随着到核心的距离呈现圈层式的空间分异规律,重要城市化地区的农产品、生态功能就近保障能力增强。(3)主体功能区布局与“双评价”和“三区三线”成果紧密衔接。

The strategic of major function-oriented zones signifies a pivotal institutional innovation in China's territorial spatial governance.Under the new territorial spatial planning system,there is an urgent need to adjust and optimize the pattern of major function-oriented zones.Comprehensive evaluation and grading were carried out by adopting a“3+N”main functional zoning system that integrates basic functions with superimposed functions,constructing an index system,and using a combination of the one-vote veto method and conditional combination method.The results show that,(1)after adjusting and optimizing the pattern of major function-oriented zones,24 counties have been added to the main agricultural production zones,51 counties to key ecological function zones,and 75 counties have been reduced in urbanized zones.The optimization plan reflects the importance attached to the goals of food security,ecological security,and intensive and efficient urban development.(2)After adjusting and optimizing the pattern of major function-oriented zones,the prominent urbanized zones present a core-periphery structure.That is,the proportion relationship among urbanized zones,main agricultural production zones,and key ecological function zones exhibits the spatial distribution law of the circle with the increase of distance from the core,enhancing the nearby guaranteed capacity of agriculture and ecological functions in prominent urbanized areas.(3)The pattern of major function-oriented zones is closely connected with the outcomes of“double evaluation”and the“three-zones and three-lines”.
