摘要
介绍了为城市政府部门服务的基于GIS的地震应急决策支持系统。该系统能评估地震的危险性 ,评定地震的破坏和损失 ,为地震应急反应和震后恢复重建提供辅助决策。本文对该系统的原理、设计准则、结构和功能作了阐述。系统分四个部分 :信息数据库系统 ;分析模块 ;决策支持子系统和系统用户界面。信息数据库系统由 68个图层构成 ;有 2 8个分析模块 ,能完成设定地震的等震线生成、场地影响分析、破坏与损失估计 ,为抢险、援救、人员疏散和其他的应急行动提供决策。最后 。
A GIS based decision making system designed for earthquake emergency response for city governments is presented in this paper The system could be used for seismic hazard assessment,earthquake damage and losses evaluation,emergency response and post earthquake recovering The principle with designing criteria,structure and functions of the system are described 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 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
