信息通信技术深刻改变了城市空间组织逻辑，并孕育出系列新空间，但目前尚缺乏系统和精细的理论解释。本文基于流空间理论，提出虚实要素融合流动视角，认为虚拟空间和实体空间的各自优势是两者融合流动的基础。在融合流动过程中，虚对实存在赋能、衍生作用；实对虚产生物化、本体作用。分处两个空间维度的虚实要素一般需要经过转换才可以耦合，完成活动闭环，本文将其称为“虚实接驳”。基于融合流动视角，界定了虚实接驳的四类要素，即在虚实空间中互为映射的虚实物品、服务、交流和人；探讨了实到虚、虚到实两种接驳方式，其中虚对实更容易刺激产生新空间、新场所。虚实要素的接驳转换将催生出虚实接驳空间，实现上述流动要素在虚实空间之间集中接入接出的枢纽型空间，并据此解读了系列典型案例。最后，本文归纳了虚实接驳引起的城乡实体空间系列变化，包括虚实接驳区位、虚实接驳集核以及城乡空间结构离散化、扁平化、单元小型化趋势，佐证该视角的实践效用。本研究成果对于丰富和深化信息时代的虚实空间互动机理，从全局视角解释信息时代新空间产生，以及把握未来城乡空间变化具有一定理论价值。

Information and communication technology has profoundly changed the logic of urban spatial organization and nurtured a series of new spaces. But there is a lack of systematic and detailed theoretical explanations for this phenomenon. This paper, grounded in the space of flows, proposes a perspective of integrated flows of virtual and physical elements, arguing that the respective advantages of virtual and physical spaces form the basis for their integrated flows. In this process of integration, the virtuality has an empowering and derivative effect on the reality; The reality generates materialization and ontological effects on the virtuality. Virtual and physical elements, existing in two distinct spatial dimensions, should undergo transformation to couple and complete the loop of activities. From the perspective of integrated flows, this paper defines the subjects of this flow as virtual-physical substances, services, communications, and people that are mutually mapped in both virtual and physical spaces. It explores two modes of conversion: from physical to virtual and from virtual to physical, with the latter is more likely to stimulate the creation of new spaces and places. The transformation and connection of virtual and physical elements will give rise to hybrid conversion spaces, which serve as hubs for the concentration of access and egress between virtual and physical spaces, and interprets a series of typical cases. Finally, the paper summarizes a series of changes in physical spaces caused by these hybrid conversion, including hybrid conversion locations, hybrid conversion centers, as well as the trends of discretization, flattening, and unit miniaturization of urban-rural spatial structure, thus demonstrating the practical utility of this perspective. The research findings contribute to enriching and deepening the understanding of the interaction mechanisms between virtual and physical spaces in the information age, providing a holistic explanation for the emergence of new spaces, and grasping future changes in urban and rural spaces, thus holding theoretical value.
