摘 要: 高密度是城市中心区发展的必然趋势,针对当前城市防灾规划的新趋向,提出以常态防灾作为城市中心区综合防灾规划的基础。从高密度城市中心区的自身属性分析总结出其灾害特征,从而构建宏观、中观、微观层次的常态防灾体系,并从用地布局、道路交通系统、开放空间、基础设施布局等方面提出规划的策略和建议,以促进高密度城市中心区防灾环境的形成。具体策略包括:在用地布局方面注意用地安全性选择并倡导用地混合和用地规模控制;道路交通系统宜选用高密度的棋盘式路网;建立与城市防灾空间相对应的开放空间体系;提升基础设施设防标准及冗余度配置。
关 键 词: 城乡规划方法与理论;高密度;中心区;常态防灾;规划策略

Abstract: High density is the inevitable trend in the development of city center. In the view of the current trend of urban disaster prevention plan, this paper puts forward normal disaster prevention as the foundation of central area comprehensive disaster prevention plan. Firstly, this paper summarizes the disaster characteristics of city center in high-density environment from its own properties, in order to build normal disaster-prevention system in macro-, meso-and micro-level. Then it gives the suggestions of central area from the aspects of land using, traffic system, open space and infrastructure layout. The strategies include the land security selection, mixed use and scale control in the aspect of land layout, choosing high-density chessboard type road network in the aspect of traffic system, building open space system corresponding to the urban disaster prevention space, and upgrading the infrastructure fortification criteria and redundancy.
Key words: urban planning method and theory; high density; city center; disaster-prevention in peacetime; planning strategy
