Abstract：
The scale of wildfire impacts to the built environment is growing and will likely continue under rising average global temperatures. We investigate whether and at what destruction threshold wildfires have influenced human mobility patterns by examining the migration effects of the most destructive wildfires in the contiguous U.S. between 1999 and 2020. We find that only the most extreme wildfires (258+ structures destroyed) influenced migration patterns. In contrast, the majority of wildfires examined were less destructive and did not cause significant changes to out- or in-migration. These findings suggest that, for the past two decades, the influence of wildfire on population mobility was rare and operated primarily through destruction of the built environment.
摘要：
野火对建筑环境的影响规模正在增加，并且在全球平均气温上升的情况下可能会继续。我们通过研究1999年至2020年间美国最具破坏性的野火的迁移影响，调查野火是否以及在什么破坏阈值影响了人类的流动模式。我们发现，只有最极端的野火（258个结构被摧毁）影响了迁移模式。相比之下,所检查的大多数野火的破坏性较小，并且不会对迁徙或迁徙造成重大变化。这些发现表明,在过去的二十年里，野火对人口流动的影响很少见，主要是通过破坏建筑环境来实现的。
