摘要
A GIS based decision making system is designed for earthquake emergency response for city governments. The system could be used for seismic hazard assessment, earthquake damage and losses evaluation, emergency response and post earthquake recovering. The principle, design criteria, structure and functions of the system are described in detials. The system is composed of four parts: an information and data base, analytical modules, a decision making subsystem and a user interface. The information and data base consists of 68 coverages, including historically and instrumentally recorded earthquakes, seismo tectonic zones, active faults, potential source areas, isoseismals of scenario earthquake, soil profiles, characteristics of buildings, and all infrastructure systems such as: transportation network (roads and bridges, culverts), oil pipeline network, gas, water, electric power, communication etc., distribution of citizens, rush repair schemes of infrastructures and so on. There are also 28 analytical modules established in the system for generating isoseismals of scenario earthquake, site effects estimation, damage and losses evaluation and decision making for rescue, relief, evacuation and other emergency response actions. As an illustration, the operation of this system for reoccurrence of a historical earthquake is demonstrated.
