In view of the great impact of urban flooding disasters on residents, traffic and urban infrastructure in recent years, we aim at finding high-risk events and loopholes in emergency plans at low cost, and simulate the emergency rescue process. According to the principles of wargame and the disaster theory, combining GIS technology and decision tree, we have established dynamic models for game pieces, rainstorm rules, visual maps and models of wargame, and demonstrated the process of urban flooding emergency rescue. Results showed that, under a 5-year rainstorm scenario and 18 deduction rounds, among the two emergency rescue action plans, our action 1 could complete the emergency rescue, but with a very high probability of loss, while action 2 could complete the emergency flooding rescue, with a small probability of loss. The application of wargame method in rescuing during urban flooding can precisely rollout the practicability of emergency plans. The results of such studies are of great significance to the training of emergency department in commanding ability, emergency management ability and decision-making ability in emergency response.
