在城市安全问题上引入“脆弱性”这一概念,初步构建城市脆弱性的研究框架:概念界定、影响因素和评价方法。城市规模、密度和形态,经济社会发展和基础设施水平以及应急管理水平,是影响城市脆弱性的结构性因素。突发事件是城市脆弱性产生的主要胁迫因素。城市规划和建设应以安全为基点,将城市脆弱性分析作为新依据,建立城市规模、密度和形态三位一体的关系,做好城市安全基础设施规划和建设,增强城市突发事件的综合应对能力。
Introducing the concept of “vulnerability ” to urban security issues, the research framework of urban vulnerability is initially established: concept definition, influential factors and evaluation methods. Urban size, density and shape, economic and social development and infrastructure levels, and emergency management levels are structural factors that affect urban vulnerability. Emergencies are the major stressors of urban vulnerability. Urban planning and construction should take safety as a starting point and take urban vulnerability analysis as a new basis to establish a trinity relationship of urban scale, density and form, do a good job in the planning and construction of urban safety infrastructure and enhance the comprehensive response ability of urban emergency.
