国际城市规划

随着信息通信技术（ICT）在日常生活中的广泛应用，城市居民日常活动与生活空间正在发生着数字化转型。本文提出包含了实体生活空间、实虚同在生活空间、实虚同步生活空间、实虚混合生活空间等概念的社区生活空间概念体系。以此为基础，采用社区居民日常活动与网络活动日志调查和GPS轨迹数据，以北京市当代—怡美社区生活圈为例，研究上述4类社区生活空间的结构特征及其内在联系，并分析实虚混合生活空间的形成逻辑。研究发现，与仅考虑线下活动的社区实体生活空间相比，同时考虑线下线上活动的社区实虚生活空间的空间分布具有明显差异。特别是与实体生活空间相比，购物、休闲、社交的实虚混合生活空间更多分布在家内和社区生活圈外，表明文化休闲、社会交往、物资购置等社区生活圈规划指南中所界定的生活圈功能可能更多被家和社区生活圈外的空间所承担，这对社区生活圈规划提出了挑战。此外，研究发现后台ICT使用所带来的线上线下活动同步发生对生活空间具有较大影响，尤其体现为上述3类活动的生活空间向社区生活圈外拓展、部分生活空间与对应类型设施无直接联系的特征。本文最后讨论了社区生活空间的实虚混合对社区生活圈规划与治理的启示。

With the widespread application of information and communications technology(ICT) in daily life, urban residents' daily activities and living spaces are undergoing digital transformation. This paper proposes a conceptual framework of community living space that includes concepts of physical living space, physical-virtual colocated living space, physical-virtual synchronized living space, and physical-virtual hybrid living space. Based on this, this paper draws upon a combined daily and Internet activity diary and GPS survey of community residents in the Beijing Dangdai-Yimei community life circle to study the structural characteristics and internal connections of the four types of community living spaces. We also analyze the formation logic of the physical-virtual hybrid living space. The research has found that, compared to the community physical living space that only considers offline activities, the spatial distribution of the community physical-virtual living space that consider both offline and online activities has significant differences. Specifically, compared to the physical living space, the physical-virtual hybrid living space of shopping, leisure, and socializing are more distributed within homes and outside of the community life circles, indicating that some functions defined by community life circle planning guidelines–such as cultural leisure, social interaction, and material procurement–may be more likely to be undertaken by home and the space outside of the life circle. This would pose a challenge to community life circle planning. In addition, the research has found that the synchronous occurrence of online and offline activities brought about by background ICT use has a significant impact on the living space, especially reflected in the expansion of the living space of the three types of activities outside the community life circle, and the lack of direct connection between some living spaces and corresponding types of facilities. Finally, this paper discusses the implications of the physical-virtual hybrid living space for the planning and governance of community life circles.
