This paper presents a generic framework and decision tools of real-time risk assessment on Emergency Environmental Decision Support System for response to chemical spills in river basin. The generic "4-step-3-model" framework is able to delineate the warning area and the impact on vulnerable receptors considering four types of hazards referring to functional area, societal impact, and human health and ecology system. Decision tools including the stand-alone system and software components were implemented on GIS platform. A detailed case study on the Songhua River nitrobenzene spill illustrated the goodness of the framework and tool Spill first responders and decision makers of catchment management will benefit from the rich, visual and dynamic hazard information output from the software.
本文提出了一种通用框架和决策工具，用于实时风险评估应急环境决策支持系统，以应对流域内的化学品泄漏。通用的“四步三模型”框架能够划定考虑到功能区、社会影响以及人类健康和生态系统这四种危害类型的警戒区和对脆弱受体的影响。决策工具包括独立系统和 GIS 平台上的软件组件。对松花江硝基苯泄漏的详细案例研究说明了该框架和工具的优势。软件输出的丰富、可视化和动态的危险信息将使泄漏应急响应者和集水区管理者受益。
