Abstract:Dynamic process of disaster spatial-temporal variation is the core processes of disaster system.Dis-aster consequences are both reflected changes over time,and sprawl in spatial region.Formulation of emergency re-sponse measures should also follow the spatial-temporal characteristics of disaster.We present a new perspective of spatial-temporal to study the variation of disasters consequence in spatial region over time,which takes hazard bear-ing body as the core and with news reports of emergencies as data source.Moreover,the rescue process of multi-stage emergency response division method was proposed.News Feature on “5·1 2 Wenchuan earthquake”from Si-na is selected for empirical analysis.The results show that,in different stages of emergencies,the focus on disas-ters hazard bearing body types and consequences are different;as emergency responses are direct at disaster conse-quences,along with which it shows chronological to a certain extent.Therefore,effective emergency response should be planned and deployed based on the law in which disaster consequences the developed and the urgency of emergency tasks.The aim of systematical rescue work and optimal allocation of emergency resources will be a-chieved.
