AI总结:

本研究利用去标识化手机数据,发现COVID-19封锁期间人类空间移动减少且伴随异步动态,解除限制后空间维度比时间维度恢复更快,且恢复程度受城市化水平和经济分层影响。

摘要:

社会经济结构与城市拓扑是人类移动模式的关键驱动因素。在2019冠状病毒病大流行期间,这些模式在其组成部分上被重塑:以日出行距离表示的空间维度,以及以通勤常规同步时间表示的时间维度。在此,利用去标识化手机用户的基于位置的数据,我们观察到,在封锁限制期间,空间移动的减少与异步移动动态的出现交织在一起。城市移动限制的解除使得空间维度比时间维度恢复得更快。此外,移动的恢复因城市化水平和经济分层而异。在城市化和高收入地区,与农村和低收入地区相比,空间移动维度遭受的破坏更小。相比之下,时间维度在城市化和高收入地区受到的影响比农村和低收入地区更大。

英文摘要:

Socio-economic constructs and urban topology are crucial drivers of human mobility patterns. During the coronavirus disease 2019 pandemic, these patterns were reshaped in their components: the spatial dimension represented by the daily travelled distance, and the temporal dimension expressed as the synchronization time of commuting routines. Here, leveraging location-based data from de-identified mobile phone users, we observed that, during lockdowns restrictions, the decrease of spatial mobility is interwoven with the emergence of asynchronous mobility dynamics. The lifting of restriction in urban mobility allowed a faster recovery of the spatial dimension compared with the temporal one. Moreover, the recovery in mobility was different depending on urbanization levels and economic stratification. In rural and low-income areas, the spatial mobility dimension suffered a more considerable disruption when compared with urbanized and high-income areas. In contrast, the temporal dimension was more affected in urbanized and high-income areas than in rural and low-income areas.
