论文摘要
社会经济结构和城市拓扑是人类流动模式的关键驱动力。在2019年冠状病毒疾病的大流行期间，这些模式在其成分中被重塑：每日行进距离所示的空间维度，而时间尺寸表示为通勤例程的同步时间。在这里，利用来自识别的手机用户的基于位置的数据，我们观察到，在锁定限制期间，随着异步移动性动力学的出现，空间移动性的降低被交织在一起。与暂时性相比，取消城市活动限制的限制可以更快地恢复空间维度。此外，根据城市化水平和经济分层，机动性的恢复不同。在农村和低收入地区，与城市化和高收入区域相比，空间流动性维度遭受了更大的干扰。相比之下，与农村和低收入地区相比，在城市化和高收入区域中，时间维度受到更大的影响。
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.
