Analysis of Natech risk response in urban areas under multi-disaster scenarios
In order to better respond to the complex multi-disaster scenarios caused by natural disasters induced technological disasters(Natech events),a method for evaluating the satisfaction of Natech risk response needs in urban areas was firstly proposed.Based on the division of urban area units,the level of risk response needs and the satisfaction of risk response re-sources within units were evaluated.The satisfaction of risk response needs in a certain area of a city in China was analyzed,and the countermeasures and suggestions were proposed.In addition,based on the urban rainstorm and waterlogging cases at home and abroad,the scenario model of rainstorm and waterlogging in urban areas was constructed using the scenario theory,and the role of risk response factors in emergency response to the multi-disaster scenario of Natech events was quantitatively analyzed.The results show that only when all types of risk response needs are met,the emergency response level can be better improved.The research results can provide scientific reference and suggestions for the risk response of Natech in urban areas under multi-disaster scenarios.
