我国北方城市暴雨灾害演化过程及风险分析
Analysis on the Risk and Evolution Process of Rainstorm Disaster in Cities of North China
摘要
Abstract
A risk analysis method based on disaster evolving network is put forward, and a risk analysis on evolution process of urban rainstorm disaster is conducted. By using complex network theory, the rainstorm disaster evolution network model is constructed, by which the rainstorm events are graded into three levels, and the relationship between levels and out-in degree of those events are discussed. Evolutionary characteristics of urban storm disaster chain and law of the consequences of the spread of storm crisis are analyzed to get the evolution chain of the key chain crisis. The results show that traffic jam is the key crisis event in urban rainstorm disaster systems,and all the evolutionary chains could be divided into short chain, long straight chain and recycle chain, in which,the crisis events in the recycle chain could induce each other and aggravate by itself, which is the crucial structure in the disaster network.关键词
