作为我国第三大经济增长极,京津冀城市群城镇等级体系的优化是区域协同发展的重要基础,将京津冀城市群城镇等级的研究范围拓展至中小城镇,参考克里斯塔勒中心地理论,运用主成分和聚类的多指标分析方法将京津冀城市群内各城镇划分为主核心城市-副核心城市-区域副中心城市-地方骨干城市-地方次级骨干城市-地方潜在骨干县市-一般县市等7个层级,系统分析京津冀城市群城镇等级体系的特点,并提出优化京津冀城市群等级体系的相关建议.
As the third largest economic growth pole in our country, the optimization of the urban hierarchy system in Beijing, Tianjin and the urban agglomerations is an important basis for the coordinated development of the region. It extends the scope of the study of the urban agglomerations in Beijing, Tianjin and Hebei to medium-sized towns and small towns, with reference to the center of Cristal Theory, using the multi-index analysis method of principal component and clustering to divide the cities and towns within the Beijing-Tianjin-Hebei urban agglomeration into the main core cities - the sub-core cities - the regional sub-centers - the local backbone cities - the local sub-key cities - the local potential backbone Counties and cities - general counties and cities at seven levels, and systematically analyzes the characteristics of the urban rating system of the Beijing-Tianjin-Zhuhai urban agglomerations and puts forward some suggestions on how to optimize the rating system of the urban agglomerations.
