Abstract：Natural, technical and man-made disasters pose enormous threats on both cities and their citizens worldwide. The concept of “urban resilience”, which is defined as the ability of an urban system and all its constituent sub-systems to maintain the necessary functions during disturbance, rapidly recover in the aftermath of the disturbance, and adapt to uncertainties in the future, brings about a new perspective of understanding disaster prevention and reduction in urban systems. In this paper, the authors propose to view a city as a system of systems in trio spaces (physical, societal and cyber spaces), and illustrate the connotation and properties of urban resilience using several sub-systems of a city and their interactions as an example. Moreover, the concept of “resilience management” is proposed, and it is advocated that only by optimal allocation of resources among different sub-systems as well as different phases of resilience (resistance, recovery and adaptation) can urban resilience be ensured and enhanced in the most effective manner.
