论文摘要
这项研究的目的是：（1）指定疏散率和家用开关稳定性为灾难期间和灾难后短期恢复的两个关键里程碑； （2）在这些关键恢复里程碑的持续时间内了解亚群之间的差异。使用具有隐私性的罚款基于位置的数据，我们在德克萨斯州哈里斯县的疏散率和居家搬出率在2017年哈维飓风中进行了研究。对于两个关键的恢复里程碑中的每一个，结果揭示了持续时间短和长期返回持续时间的区域，并能够评估疏散返回和家庭开关稳定性模式的差异。实际上，洪水泛滥地区的关键恢复里程碑指标的持续时间较短，这不一定是积极的迹象。较短的疏散率可能是由于疏散障碍和低收入居民的房屋搬出率返回较短，这与住在租赁房屋中有关。此外，在所有亚种群组中都观察到了疏散返回和家庭开关稳定性的偏斜和不均匀的恢复模式。所有返回模式均显示两相返回进度模式。这些发现可以告知灾难经理和公职人员以更积极，数据驱动和公平的方式进行恢复监控和资源分配。
The objectives of this study are: (1) to specify evacuation return and home-switch stability as two critical milestones of short-term recovery during and in the aftermath of disasters; and (2) to understand the disparities among subpopulations in the duration of these critical recovery milestones. Using privacy-preserving fine-resolution location-based data, we examine evacuation return and home move-out rates in Harris County, Texas in the context of the 2017 Hurricane Harvey. For each of the two critical recovery milestones, the results reveal the areas with short- and long-return durations and enable evaluating disparities in evacuation return and home-switch stability patterns. In fact, a shorter duration of critical recovery milestone indicators in flooded areas is not necessarily a positive indication. Shorter evacuation return could be due to barriers to evacuation and shorter home move-out rate return for lower-income residents is associated with living in rental homes. In addition, skewed and non-uniform recovery patterns for both the evacuation return and home-switch stability were observed in all subpopulation groups. All return patterns show a two-phase return progress pattern. The findings could inform disaster managers and public officials to perform recovery monitoring and resource allocation in a more proactive, data-driven, and equitable manner.
