国土空间规划视角下城市高质量发展路径分析——以我国“两横三纵”城市化地区为例

Analysis of Urban High-quality Development Path from the Perspective of Territorial Space Planning:A Case Study of China’s“Two Horizontal and Three Vertical”Urbanized Areas

研究目的:开展国土空间规划视角下我国“两横三纵”城市化地区高质量发展路径研究。研究方法:综合指数评价法和SOFM网络模型。研究结果:(1)我国“两横三纵”城市在国土空间视角下的高质量发展仍有较大提升空间,除沿海纵轴(L1)和部分节点城市发展质量水平较高外,其他轴线城市发展质量均呈现显著的空间异质和低质特征;(2)国土空间结构和效率是城市高质量发展的主要限制因素,但不同城市存在差异,整体看优化开发区主要面临国土空间结构优化问题,重点开发区则更应重视国土空间效率提升;(3)综合城市高质量发展水平与主体功能类型,将研究区划分为优化开发区结构提升优质区、重点开发区结构提升优质区等7类空间治理模式区,并结合“两横三纵”轴线分类提出了城市高质量发展的综合治理路径。研究结论:未来应分区分类推进“两横三纵”城市高质量发展,精准施策提升国土空间治理水平。

The purpose of the study is to explore high-quality development path in China’s“two horizontal and three vertical”urbanized areas from the perspective of territorial space planning.The research methods include entropy evaluation and SOFM network analysis.The results show that:1)China’s“two horizontal and three vertical”distribution cities still have a lot of room for improvement from the perspective of high-quality development of territorial space.Except for the coastal vertical axis(L1)and some node cities with high development quality level,the development quality of other axis cities shows significant spatial heterogeneity and low-quality characteristics.2)Territorial space structure and efficiency are the main constraints to high-quality urban development,but they vary from cities.Overall,the optimized development zones mainly face the problem of optimizing territorial space structure,while the key development zones should pay more attention to the improvement in territorial space efficiency.3)By integrating the level of highquality urban development and the type of main function,the study area is divided into seven types of spatial governance mode zones,including optimized development zone structure enhancement high-quality zone,key development zone structure enhancement high-quality zone,etc.,and categorizes the comprehensive governance path for high-quality urban development in combination with the“two horizontal and three vertical”axes.In conclusion,China should promote the high-quality development of“two horizontal and three vertical”cities by zoning and categorization in the future,and enhance the level of territorial space governance by precise measures.
