武汉远城区吸引力的要素识别和规划优化——以东西湖区为例

The Feature Extraction for Attractiveness and the Optimization of Planning in a Suburban District: A Case Study of the Dongxihu District in Wuhan

疏解中心城区人口,改善远城区的居住和就业条件,促进其人口和产业的集聚发展,是国内外城市共同面对的课题。既有研究表明,合理规划远城区的公共服务设施并优化其产业空间布局,是引导中心城区人口向远城区疏解的着力点。以武汉东西湖区为研究对象,首先开展文献收集、问卷调查、实地踏勘和数据收集;其次通过综合分析,找出与城市规划有关的吸引力的规律,建立武汉远城区人口吸引力的评价指标体系;再者利用多元回归模型,识别显著要素,确定模型和要素的空间效应;最后通过对比要素的空间效应和原有规划方案,提出规划建议,改进和完善规划的评估和优化工作。

Relocating population from the central city, promoting the development of industry, facilitating the agglomeration of economics, and increasing the concentration of population in suburban districts are important topics for cities all around the world. The existing literature shows that the rational planning and proper layout of urban public service facilities are the key points for planning and guiding the spatial allocation of urban population. This paper intends to identify and extract the key elements for attracting population and optimizing control regulations in a suburban district. It employs the Dongxihu District in Wuhan as an empirical case. Traditional OLS and step-wise regression models are utilized to examine the relationship between population increase and the key elements and sort out the major contributors. Geographically Weighted Regression(GWR) model is employed to find out their spatial effects. The findings have been used to guide the optimization of control regulations in suburban districts.
