Analysis of Regeneration Strategies of Small and Medium-sized Cities in Urban Agglomerations:Taking the Public Space of Xushui District in the Beijing-Tianjin-Hebei City Cluster as an Example

“城市群”是我国城镇化体系的主体形态和城镇人口的主要空间载体,城市群内的中小城市与核心城市一样肩负着重要的时代使命。以徐水区为例,探讨京津冀城市群内的中小城市如何通过城市更新传承保护城市历史文化、优化城市公共空间、提升城市景观风貌。提出徐水公共空间城市更新技术路线,就城市文化在公共空间表达、街道空间优化、口袋公园营建、门户景观提升等4项景观策略进行详尽阐述,并总结出文化传达的独特性、公共空间提升的节约性、城市景观风貌塑造的特色性、科技赋能的示范性等在京津冀城市群内中小城市实施公共空间更新中可推广的景观策略。

Urban agglomerations are the main form of urbanization system and the main spatial carrier of urban population in China.The small and medium-sized cities in urban agglomerations shoulder the important mission as the core cities.Taking Xushui district as an example,this paper discusses how small and medium-sized cities in the Beijing-Tianjin-Hebei city cluster can protect urban history and culture,optimize urban public space,and enhance urban landscape through urban renewal.This paper puts forward the technical route of urban renewal in Xushui public space,and elaborates four landscape strategies,namely,expression of urban culture in public space,optimization of street space,construction of pocket park,and enhancement of portal landscape.And it summarizes the uniqueness of cultural communication,the economy of public space enhancement,the characteristics of urban landscape style shaping,and the demonstration of scientific and technological empowerment in the implementation of urban renewal of smalland medium-sized cities in the Beijing-Tianjin-Hebei city cluster.
