都市防災システム論

Abstract

From the view point of analogy between human body and urban structure, we discussed about what is the missing function in our urban disaster prevention and how to respond to complex disasters due to over-dense and huge population in mega cities.The system of homeostatis is applicable to urban disaster prevention systems.The self-detecting and self-defensive functions in lifeline network systems are exclusively required to realize quick action of disaster prevention activities.Centralized disaster information systems at the present, therefore, has to be improved because it operates only under some ideal conditions.Even if it focuses on property damages, it takes too much time to repair or to recover.The disaster preventive force can be defined as the function of population density and amount of revenue in every large city.This criterion is applicable for the classification of urban natural disasters.
