空间经济绩效导向下的城市用地布局优化研究

A STUDY ON THE OPTIMIZATION OF URBAN LAND LAYOUT UNDER THE GUIDANCE OF SPATIAL ECONOMIC PERFORMANCE

空间绩效是衡量城市用地布局合理与否的重要内容。本文基于我国城镇化质量提升的转型发展背景,提出空间经济绩效导向下的城市用地布局优化研究思路,即在定量研究分析城市空间经济绩效的基础上,通过经济绩效和绩效空间的耦合分析,判读出城市绩效样本空间(高效空间生成元)和改进需求空间的分布情况,并以此作为构建新的城市空间经济绩效网络的依据,最后在地方制度环境和社会环境的约束下提出城市用地布局的优化方案。研究将这一理念和方法运用于宁夏固原市的案例研究中,结果表明:该方法能够较好地实现研究定量化和空间可视化,并为城市用地的优化布局提供方法支撑。

Spatial performance is an important indicator for measuring whether urban land layout is reasonable or not. In the context that China's urbanization is transforming from "quantity" to "quality" development, this paper puts forward the research method of spatial economic performanceoriented urban land layout optimization. In other words, on the basis of the quantitative study of spatial economic performance and coupling analysis on economic performance and spatial performance, the paper finds the distribution of sample space and space needed to be improved. With that as the basis for building a new city space network of economic performance, it proposes the optimization scheme for urban land layout under the constraints of local institutional and social environment. It then applies the method to study Guyuan City, Ningxia, and the results show that this method can achieve the quantitative research and spatial visualization, and provide a method for optimizing urban land layout.
