Abstract: With the implementation of urban revitalisation, the daily needs of urban residents in older areas represented by Chen Clan Temple Street, Guangzhou were analysed based on the theory of spatial production and the renewal of old urban spaces in accordance with needs of diverse groups. Based on literature reviews, field surveys and questionnaires, it was found that users of old urban spaces have dual demands in terms of social life and cultural travel. These users mainly include native populations (based on local birthplace and registered residence), new urban populations (based on birth in other locations, but registered in the local area), and urban floating population (with external birthplace and registered residential address). Specifically, the native and new urban populations relate to daily life and social communication. They utilise urban living space under four dimensions: leisure and recreation, elderly services, parent-child interaction, and convenient shopping. Urban floating population is divided into nearby working groups and groups of cultural and tourism consumption. The demands of the former group for daily living space are few and involve only leisure and recreation. The latter group is often characterised by instantaneous spatiotemporal aggregation and the need for internet, which shows a spatiotemporal mismatch with neighbourhood residential communities. Hence, the dual coordination between lifestyle and cultural tourism among different users in the new round of urban renewal programme requires attention. In this study, a case study was conducted based on Chen Clan Temple Street in Guangzhou. The study area includes a borderless street prototype involving "1" living area, "1" cultural and tourism streets and "N-points" urban cultural and tourism nodes formed by "urban living space" and "urban cultural tourism space". During urban renewal, it is necessary to classify and implement the transformation of urban living space by improving the quality of social space. First, the urban living space for leisure and recreation should be reconstructed based on social relationships. Areas for leisure based on the phased use and disassembled facilities should be constructed in accordance with spatial use practice of different groups. Second, it is necessary to reconstruct urban living space for social communication by improving the original scenes. It should retain the original areas for social communication, restoration of urban living, and congregation of different groups. The demand for urban cultural and tourism space has been updated based on three measures, namely, "land use control", "construction control" and "business access". Further, “linear spaces" (streets for current urban culture and tourism) and "point spaces" (idle spaces in blocks) should be constructed. "Land use control" mainly regulates the extent of commercial space used. It is focused on commercial industries scattered into scaled urban commercial spaces by emphasising on activities of daily life in the block. It also highlights differential development and mixed use, and ensures that the residential space for daily life in the block is not restricted. The "construction control" ensures reasonable transformation of existing urban spaces according to emotional elements of markets, and reasonable spatial reconstruction based on the control of elements, colors, and other parameters. "Business access" creates a consumption industrial space centred on the local consumption and maintains the authenticity of market space by preserving the local industry in the block. The old urban space represents the unique features of the city. It is not only an important factor associated with urban passion, but also a key element in the current urban renewal mechanism. The update mechanism proposed in this study provides a new idea for the reconstruction of market space, and enhances the strategy for the update of inventory in old urban area. It also provides a new strategy for the next stage of urban upgrade and cultural protection in the old urban areas. However, further studies are needed to implement specific spatial designs and policies.

摘要： 以广州陈家祠街区作为案例，对老城区市井生活群体及其空间使用需求进行分类，揭示老城区市井群体的生活需求，探索面向多元群体需求下老城区市井空间的更新模式，并开展匹配不同群体需求的市井空间改造研究。通过文献综述、实地调研与问卷调查，发现不同群体对老城区市井空间有着社交生活与文旅消费的双重需求，其更新可进一步强化“1”个生活片区、“1条”市井文旅街巷与“N”点市井文旅节点的无边界空间模式。此模式提供了市井空间更新改造的新思路，完善了老城区存量空间更新设计方法，也为下一阶段城市更新行动保护老城区市井文化探索了新的实施路径。
