中国城市发展格局优化的科学基础与框架体系

The Scientific Basis and Systematic Framework of the Optimization of Chinese Urban Development Pattern

城市发展格局是基于国家资源环境格局、经济社会发展格局和生态安全格局而在国土空间上形成的等级规模有序、职能分工合理、辐射带动作用明显的城市空间配置形态及特定秩序。科学合理的城市发展格局对推动国家城镇化健康发展,提升城镇化发展质量,对加快国家现代化进程都具有十分重要的战略意义。正由于如此,党的十八大报告和中央经济工作会议等国家重要文件和国家重大规划都多次提出要构建科学合理的城市化格局和城市发展格局。文章系统分析了指导中国城市发展格局优化的公平优先理论、格局优化理论、流空间理论、国土三生空间优组理论、均衡网络理论和空间信息系统理论等六大科学理论;构建了由2个宏观层次、8个中观层次和15个微观层次组成的中国城市发展格局优化的系统框架体系;通过不同空间尺度的格局优化,将形成科学合理的城市发展格局和安全的国土空间开发格局。

Urban development pattern is an urban space form and certain order with rational and orderly scale, proper division of functions and prominent influence of radiation, which is based on the patterns of the national resources and environment, the economic and social development, and the ecological security. And a scientific and rational urban development pattern is indeed of great strategic importance to promoting the healthy development of China＇ s urbanization, improving the quality of urban development, and accelerating the modernization process. Therefore, to construct a scientific and rational urban development pattern has been proposed in several key government documents and major planning papers such as the report to the Eighteenth National Congress of the CPC and the Central Economic Working Conference. This paper systematically analyzes the six scientific theories （i.e., the priority of fairness theory, the pattern optimization theory, the space of flows theory, the optimized combination of ＂ecology, production and living＂ space theory, the balanced network theory, and the spatial information system theory） that guide the optimization of China＇s urban development pattern, and constructs a systematic framework of China＇ s urban development pattern on the levels of two macro stages, eight middle stages and fifteen micro stages. Through these optimizations of development pattern at different ：spatial scale, the scientific and rational urban development pattern and safe national space development pattern will be established.
