Disaster Situation Awareness:Research Review and Prospect
Disaster situational awareness is the basis and prerequisite for an effective response to disasters,and it is a key link in promoting advanced prevention and a downward shift of the focus of disaster management.According to the logic frame of"theory-methodology-application",the connotation and modeling framework of disaster situational awareness are sorted out.The progress of disaster situational element extraction,element fusion,situational assessment,and situational derivation methods are summarized.The practical application of disaster situational awareness theory and methods is ex-plained.It is found that research in this field still has shortcomings such as research scenarios focusing on a single event,theoretical research favoring the individual level,methodological research focusing on data extraction and fusion,and ap-plied research focusing on specific problem-solving.In the future,it is necessary to focus on the development of a human-machine-object cooperative theory system,holographic technology and methodology system,and application system for emergency decision-making,to further enrich the theoretical innovation and knowledge system of disaster situational aware-ness research.
