摘　　要：本文以应对突发事件的城市中心区安全规划与设计为研究对象,通过文献回顾、论证了应当建立以步行疏散为主要思路的备灾体系。步行疏散备灾空间既是城市交通空间,又是灾时人员疏散的承载体,在城市设计层面的防灾规划中应作为重要设计内容加以考虑。然而我国尚缺乏在城市设计层面的城市中心区安全疏散空间设计指导法规。本文提出了基于分期和分层理念的城市中心区突发事件步行疏散备灾空间设计研究框架,以期补充和完善我国城市中心区安全设计理论,并为后续研究提供指引。In this paper,the safety planning and design of Urban Central Areas(UCA)in response to emergency events are taken as the study object.It is confirmed by the literature review that a walk out plan should be considering as the main ideas to establish the disaster preparedness system.In this system,the pedestrian evacuation space serves as the city traffic space and the life path during emergency,which should be designed in detail on an urban design level.But currently,there is no corresponding guidance in the urban design level.This paper proposes a research framework for the planning and designing of UCA in response to emergency events based on the staging and stratification concept,with a view to supplementing and perfecting the safety design theory of UCA in China and providing guidance for the future study.
