【摘要】 为探究突发公共卫生事件对城市居民广义游憩行为的影响，本研究以2021年7月江苏省南京市的新型冠状病毒（COVID-19）感染事件为例，利用手机信令数据，分析事件前后城市居民游憩行为的空间分布和时序变化特征，并通过双重差分法探究分级疫情管控政策对游憩行为的影响。研究发现：本轮感染事件发生后，居民的游憩出行频次明显减少、出行平均距离有所增加；所有4类游憩目的地（自然生态类、商业娱乐类、文化休闲类、体育健身类）的出行频次在事件后均有所减少；在出行平均距离方面，指向自然生态类和体育健身类游憩目的地的出行平均距离呈现增加趋势，指向文化休闲类和商业娱乐类游憩目的地的出行平均距离则在事件后呈现一定程度的减少趋势。研究结果表明，分级管控政策对于不同类型的游憩行为影响程度各异。研究探讨了突发公共卫生事件下城市居民广义游憩行为的时空模式和机制，可为城市游憩空间规划提供参考。更多还原

【Abstract】 In order to investigate the impact of public health emergencies on the “general recreational behaviors” of urban residents, this researchtakes the COVID-19 outbreak event in Nanjing of China in July 2021 as an example, based on cell phone signaling data, analyzes the spatial distribution and temporal changes of urban residents’ recreational travel behaviors before and after the outbreak, and then explores the impact of the hierarchical control policies on recreational travel behaviors via Difference-in-Differences(DID) method. It has found that after the outbreak, residents’ recreational travel frequency decreased significantly and their average travel distance increased; the frequencies of travel to all four types of recreational destinations decreased after the outbreak; in average travel distance, those to natural attractions and sports/fitness destinations tended to increase, while those to cultural leisure as well as commercial entertainment destinations tended to decrease after the outbreak. Further results indicate that the hierarchical control policies had varying degrees of impact on different types of recreational travel. This research provides an interpretation on the spatio-temporal pattern and mechanism of urban residents’ general recreational behaviors under public health emergencies, which can provide a reference for planning of urban recreational space.更多还原
