The frame design of prefecture-level post-earthquake emergency decision support system

Post-earthquake emergency decision support system was an emergency command and service system, which rapidly obtained information about the economic losses, casualties, space distribution and other situations of the disaster area and provided different decision-making suggestions needed in the earthquake relief work. The research, based on geographic information system technology, raised the design thoughts and techniques of building prefecture-level post-earthquake emergency decision support system. The research adopted the modularized overall structure, divided the system into five subsystems including foundation database, information analysis and processing, earthquake disaster losses evaluation, information interaction platform and disaster relief assistant decision making. The research explained the design thoughts of all subsystems and their main functions which need to be achieved. The research provided beneficial reference for the prefecture-level earthquake prevention and disaster reduction information construction.
