Research on Judgment Methods for Regional Search and Rescue Priority in Earthquake Disaster Areas and its Application——Taking Wenchuan M8. 0 Earthquake as an Example

To meet the demand of fast response and emergency assistant decision making,considering population quantity,population density,terrain,traffic,weather,intensity and other factors in earthquake disaster area,we build the judgment model of regional search and rescue target priority in earthquake disaster areas. Then taking Wenchuan M8.0 earthquake as an example,we give the priority classification of search and rescue target. The result shows that this method could meet judgment need of regional search and rescue target priority in the large disaster area.
