应用Arcgis实现地震次生毒气泄漏与扩散的模拟演示

摘要

本文主要针对破坏性地震中由次生灾害引发的毒气泄漏和扩散进行研究，采用国内普遍应用的数据模型进行计算，并通过Arcgis软件实现毒气泄漏与扩散的模拟演示，该成果是城市防震减灾信息管理系统的重要组成部分，能够对事故应急决策提供参考依据，对城市综合防御与减轻城市和大型企业的地震次生毒气泄漏与扩散灾害都具有重要的意义。%　　The thesis maily focuses on the study of poison gas leakage and diffusion caused by secondary disaster in destructive earthquake, calculates by using commonly used data model in China and realises simulation demonstration of poison gas leakage and diffusion through Arcgis software. This achievement is an important part of the information management system of urban earthquake prevention and disaster mitigation, which is able to provide a reference for emergency decision, and is of great importance of urban comprehensive defense and mitigating city and large enterprises' secondary poison gas leakage and diffusion caused by earthquake.
