一种基于宏观经济指标的地震灾害快速评估方法及实现
|
摘要
利用Matlab软件及Office组件函数编写了基于宏观经济指标进行地震灾害快速评估并自动生成灾害简报的程序。该程序可以充分利用天津地区高密度强震台网资源,也可以计算理论烈度下的灾害评估结果。程序利用的基础数据资料主要是乡镇级别的人口及区县级别的GDP统计数据,数据更新维护经济可靠。通过与天津市"十五"地震应急评估系统触发的342个地震灾害评估结果对比,表明二者之间相关性非常强,而该程序计算速度则快一个量级以上。程序涉及的数据处理及计算方法适合于大城市及城市群的地震灾害快速评估。
Matlab software and Office subassembly function are used to compile a computer program,which can evaluate earthquake disasters according to macroeconomic indicators and automatically produce a WORD report for the evaluation results. This computer program not only can make full use of resources of high-density strong earthquake network in Tianjin area,but also can get evaluation results based on theoretic calculated intensities. Foundational data used in the program are mainly statistical data concerning population of towns and GPD of counties,and could be maintained and renewed reliably and economically. According to comparison of evaluation results of the program and of 342 artificial earthquakes in earthquake emergency evaluation system in the 10th Five- year Plan in Tianjin,it is shown that the system and the program are closely correlated,but the calculating speed of the program is faster one order of magnitude. Data processing and calculating method presented in the program is suitable for quick evaluations on earthquake disasters in big cities and city clusters.
