应对突发公共卫生事件的城市形态与交通可达性评价研究——以河南罗山县为例

Evaluation of Urban Form and Traffic Accessibility in Response to Public Health Emergencies:Taking Luoshan County in Henan Province as an Example

新型冠状病毒肺炎疫情的发生严重影响了城市的正常运行,居民在城市街道空间聚集流动会加速疫情的传播。文章以河南省罗山县为例,基于空间句法理论,分析罗山县的城市空间交通可达性。研究发现,灵山大道与龙山大道等路段有着较高的交通潜力,在空间上会产生人流聚集现象。通过对城市活力空间提出有效的交通管理建议,从物理空间隔绝的角度控制疫情传播,以期为应对未来突发公共卫生事件提供参考。

The coVID-19 outbreak has seriously affected the normal operation of the city,and residents gathering and flowing in the urban street space will accelerate the spread of the epidemic.Taking Luoshan County in Henan Province as an example,the paper analyzes the accessibility of urban space traffic based on space syntax theory.The study found that Lingshan Avenue and Longshan Avenue have a high traffic potential,and people will gather in the space.By proposing effective traffic management suggestions for the urban vitality space,the epidemic spread can be controlled from the perspective of physical space isolation,so as to provide references for dealing with future public health emergencies.
