全球应对COVID-19大流行的行动给人类流动模式和工作环境带来了重大变化。我们的目的是探讨在挪威奥斯陆部分封锁期间，社会距离措施如何影响城市绿地的娱乐使用。来自数千名游憩者的移动跟踪数据被用来分析活动的高分辨率时空变化。我们估计，相对于3年同期的平均水平，封锁期间的户外娱乐活动增加了291%。在对当时的天气和一年中的时间进行调整后，这一增长明显大于预期，相当于大约。在市区（人口69万）每天增加8.6万项活动。行人（步行、跑步、徒步旅行）和骑自行车的人似乎都在绿色景观和树冠覆盖率较高的步道上加强了活动，但反应的差异受到步道可达性和社会距离偏好的调节。增加的幅度与小径的偏远程度呈正相关，这表明绿地促进了社会距离，并间接缓解了COVID-19的传播。最后，城市公园、城郊森林和保护区的行人活动增加，突出了进入建筑矩阵中交织在一起的绿色开放空间的重要性。这些发现揭示了城市自然在危机时期作为弹性基础设施的价值。当前的大流行病还揭示了我们在为未来可持续城市进行城市规划的道路上可能面临的一些重要困境。
The global response to the COVID-19 pandemic has brought with it significant changes to human mobility patterns and working environments. We aimed to explore how social distancing measures affected recreational use of urban green space during the partial lockdown in Oslo, Norway. Mobile tracking data from thousands of recreationists were used to analyze high resolution spatio-temporal changes in activity. We estimated that outdoor recreational activity increased by 291% during lockdown relative to a 3 yr average for the same days. This increase was significantly greater than expected after adjusting for the prevailing weather and time of year and equates to approx. 86 000 extra activities per day over the municipality (population of 690 000). Both pedestrians (walking, running, hiking) and cyclists appeared to intensify activity on trails with higher greenviews and tree canopy cover, but with differences in response modulated by trail accessibility and social distancing preferences. The magnitude of increase was positively associated with trail remoteness, suggesting that green spaces facilitated social distancing and indirectly mitigated the spread of COVID-19. Finally, pedestrian activity increased in city parks, peri-urban forest, as well as protected areas, highlighting the importance of access to green open spaces that are interwoven within the built-up matrix. These findings shed new light on the value of urban nature as resilience infrastructure during a time of crisis. The current pandemic also reveals some important dilemmas we might face regarding green justice on the path towards urban planning for future sustainable cities.
