Regional Disaster Loss Risk Assessment Modeling with Destruction Mode of Elements at Risk
Emergency events,especially the concurrent disaster and chain-style disaster,has brought numerously lost for life and economy.Meanwhile,the complexity and diversity of regions where the disaster occurs make disaster loss being in uncertainty.Research on disaster loss risk will promote disaster prevention and mitigation with much pertinency to minimize loss better and protect peoples lives and property.Due to various disasters and regions,it is more appropriate to assess regional potential disaster loss according to its formation mechanism.Directed by disaster system theory,investigate destructiveness of elements at risk based on hazardous basics(material,energy,information)and then analyze the acceleration of elements at risk and their corrections for loss spread and identify rules of disaster loss diffusion with destruction mode of elements at risk.Discuss the potential threat resulted by damaged elements through a disaster loss risk assessment model,and the model tested by different simulation scenarios is effective and helpful to predict possible danger for diverse regions.
