城市空间聚集的安全风险及其防控——以新冠肺炎疫情防控与应对为例

Security Risks of Urban Spatial Agglomeration and Their Prevention and Control--Based on the Prevention and Control of the COVID-19 Epidemic

新冠肺炎疫情的肆虐,需要从不同视角加以审视。从城市空间格局和城市形态的视角,城市的空间聚集、城市空间格局的极化、城市空间规划的中心化理念,是疫情传播放大、灾害影响加剧的客观条件。需要检讨空间聚集理念下城市空间规划所形成的可能助推疫情的传播和扩散的机理和效应。鉴于城市人口在空间聚集形态下疫情传播快、灾害重的情况,城市空间规划需要权衡经济理性、生态理性和安全理性,将安全理性放在优先位置。

The rampant COVID-19 epidemic needs to be examined from different perspectives.From the perspective of urban spatial pattern and urban form,the urban spatial agglomeration,polarization of urban spatial pattern,and the concept of centralized urban spatial planning are the objective conditions for the spread of the epidemic and the aggravation of its impact.It is necessary to review the mechanism and effect of urban spatial planning based on the concept of spatial agglomeration that may encourage the spread of the epidemic.Considering the rapid spread of the epidemic and serious outcome due to the spatial agglomeration,urban spatial planning needs to balance economic rationality ecological rationality and security rationality and make security rationality the top priority.
