城市灾害综合风险管理的三维模式--阶段矩阵模式

在考虑防灾减灾措施下,构建了城市灾害风险综合评估的框架体系,包括11种城市灾害所对应的风险系统评估后的综合评估,每个系统的评估是在考虑防灾减灾措施下采用信息扩散技术进行的信息处理和评估.在综合评估的基础上提出了由阶段、灾害风险种类和级别组成的城市灾害综合风险管理的三维模式--阶段矩阵模式.它是由3个阶段、6个环节及每个环节的矩阵模式组成.据此,简述了城市灾害综合风险管理的过程是灾前预防矩阵管理、灾前准备矩阵管理、灾中应急矩阵管理、灾中救援矩阵管理、灾后恢复矩阵管理和灾后重建矩阵管理不断循环和完善的过程.最后,用一个虚拟实例说明了阶段矩阵模式的有效性.

Three dimensional mode for integrated risk management of urban disaster: stage matrix pattern

In this paper,the framework system of general evaluation for disaster risk in city is devised,considering measures of disaster prevention and mitigation and applying information diffusion technique,which includes evaluations of eleven disaster risk systems.In succession,based on it,three dimensional mode serving for integrated risk management of city disaster is put forward which is a stage matrix pattern,and made of 3 stages 6 links and the matrix patterns for each link.According to these,management process of disaster integrated risk is a continuously cyclic and perfect process of prevention matrix management and preparation matrix management before disaster,(emergency) matrix management and rescue matrix management in disaster,recovery matrix management and reconstruction matrix management after disaster.At last,the validity of the stage matrix model is illustrated with a virtual example.
