摘　　要：中国大城市目前所经历的发展变迁可能是城市建设最具可变性的阶段。利用这一阶段的优势,城市建设者的核心任务之一就是建设"无缝"城市,亦即减少城市中各个实体边界所造成的阻抗效应。英国和欧洲城市的经验教训说明提高城市密度、建设紧凑城市的做法亟需考虑城市活动密度增加是否会导致缝隙效应的恶化。新近正在涌现的车辆控制技术和协调城市基础设施建设的新做法都是减少城市缝隙效应的契机。Most large cities in China are experiencing a transitional stage when physical growth may be at its most fluid, with multiple urban centres competing for growth. One of the central tasks at this stage is to aim for seamlessness in cities, i.e. to reduce the impedance effects caused by visible and invisible boundaries between urban entities. The lessons from cities in the UK and European cities suggest that compacting urban activities in cities needs more careful consideration： the agglomeration benefits that arise from densification can only be achieved if the impedance effects are effectively addressed. Emerging technologies in vehicles and a new philosophy in coordinating urban infrastructure development can provide new triggers for transforming how we live and work in the urban environment.
