【摘要】 目前应急平台能力建设已成为应急管理的一项重要基础性工怍,而模拟仿真软件作为应急平台不可缺少的组成部分也引起了人们的广泛关注。文章介绍了一套自主开发的辐射突发事件模拟仿真系统软件,该系统以北京市区作为研究示范区域,通过采用源项设置模块、剂量转换模块,结合城市边界层小尺度模式和随机游走扩散模式,实现了在地理信息系统(GIS)上模拟"脏弹"爆炸后放射性污染物在大气中的输运过程,为早期应急和后果评价提供了技术支持和参考,为后续研究提供了有用的借鉴。更多还原

【Abstract】 Nowadays,with the emergency response capacity building has been becoming an important basic work of the emergency management,more attention was paid to simulation software which is a must portion of the emergency response platform.In this paper,a GIS-based radiation incidents simulation system software is introduced.This system taking Beijing City as the demonstration area,establishing the source term setting module,the dose conversion modul and customizing the small-scale urban boundary layer model and the random walk atmospheric diffusion model.It can simulate transport processes of radioactive pollutants in atmosphere after dirty bomb explosion in Beijing.The results of this study can not only provide technical support and reference for the emergency decision-making and consequences assessment, but also provide a useful reference for the follow-up study.更多还原
