摘要
应急疏散是减少突发事件情况下人员伤亡和生命财产损失的重要手段,疏散决策的科学性至关重要,实现应急疏散应用模型与GIS的集成是提高应急疏散决策效率和水平的关键。本文根据城市应急疏散决策需求,设计了突发事件模型库,基于模型库对城市应急疏散GIS进行了设计。以有毒气体泄漏和爆炸为例进行了实验模拟,实验表明在模型库支持下的城市应急疏散GIS的辅助决策功能显著提高。
：Emergency evacuation is an important measure to reduce the life and belongings loss when emergency happens, the scientificalness of evacuation decision-making is extremely significant, realizing the integration of emergency evacuation application and GIS is the sticking point which can improve the efficiency and level of emergency evacuation decision-making. This paper designed the emergency model base and the urban emergency evacuation GIS based on model database according to the requirement of urban emergency evacuation decision- making. A simulation experiment with nocuous gas leakiness and blast indicates the assistant decision-making ability of urban emergency evacuation GIS is advancing markedly supported by the model base.
