【摘要】 针对我国国情和区域空间特征,提出立足于美好人居环境建设的“国家空间规划论”,从理论上提出国家城镇空间的构建要以生态安全为前提,形成由差异性空间资源分析、适应性空间结构布局和动态性监测评估优化构成的区域空间理论认识,并随着城镇化进程的不断推进和所面临问题的不断变化,将其内涵不断拓展和完善。以此为基础,提出精准分析与适应性技术的区域空间优化方法,从自然生态、安全风险两个维度,构建由区域精准分析、适应性空间规划、动态性监测评估优化等三大技术构成的全周期的区域空间优化技术体系。以20年来多个不同尺度的区域性规划实践为例,阐述该方法的具体应用。更多还原

【Abstract】 Given China’s national and regional spatial characteristics, the paper puts forward a "national spatial planning theory" aiming toward building a beautiful living environment. The proposed national spatial planning theory advocates that China’s national urban system should be based on the premise of ecological security and reflects theoretical understandings in different spatial resources, adaptive spatial structures, and processes of dynamic monitoring, evaluation and optimization. As urbanization continues and problems confronting societies change, the scope of the theories will keep expanding. Based on this understanding, a regional spatial optimization method of precise analysis and an adaptive technology are proposed. By taking into consideration of the ecological system and security risks, the paper constructs a full-cycle regional spatial optimization system composed of regional precise analysis, adaptive spatial planning, and the process of dynamic monitoring,evaluation and optimization. Finally, drawing examples from regional planning practices at different scales in the past 20 years, the paper expounds the application of the proposed method.更多还原
