The Study of City Dynamic Administrate Information System of Anti-Seismic and Disaster Mitigation

The earthquake disaster is a serious natural disasters . Cause huge casualties and property losses due to its sudden , often in a very short period of time , and may lead to secondary disasters , as well as the broader social disaster . Geographic information system was introduced into the field of disaster prevention and mitigation , by static Planning to dynamic management , and to contribute to raising the level of the city's disaster prevention and mitigation , and the concept of updating . How to predict the results based on a regional level of economic losses in future earthquakes , dynamic updates , emergency decision for earthquake disaster reduction countermeasures taken at this stage there is a great reference for policymakers . Hebei Institute of the test area , the buildings on the test area , indoor property , casualty and other losses in the different seismic intensity projections made, and geographic information system (GIS) manifested intuitive graphical way . In this paper, the spatial analysis capabilities of GIS , zoning analysis of earthquake damage prediction results , to distinguish the difference between different locations of seismic hazards . The earthquake loss forecast calculation methods and calculation results, given the various structures housing destruction of economic losses , indoor property damage , casualties spatial distribution . The main significance of this analysis is to be able to fully understand the spatial distribution of the test area earthquake potential disasters , as before the earthquake to take the appropriate precautions and post-earthquake emergency rescue work to facilitate . This article can be convenient , fast access to the test area buildings , indoor or property and personnel distribution , and can be based on the data changes , the dynamic display . GIS, graphics and links and cross- check of the property , an update of the data through GIS thematic maps drawn while the graphics update , to achieve real-time updates of the entire system , to arrive at different forecast loss of visual performance . Instance of Hebei Institute of Technology for a typical cell for the overall urban earthquake disaster prevention dynamic management methods and techniques of earthquake disaster prevention to the dynamic management of the transition from a static planning and goal of the combination of professional planning and urban development will great benefit.
