在全球和美国，野火对人们及其家园构成越来越大的风险。野火管理假设建筑物主要在荒地-城市界面（WUI）燃烧，其中房屋直接点燃（特别是在混合WUI地区，房屋和荒地燃料混合），或通过火把，对界面WUI（荒地燃料最少的地区，但靠近密集的荒地植被）中的建筑物构成主要威胁。然而，即使是城市地区也可能遭受野火的袭击。我们研究了加州（1985-2013）近三十年来城市、农村和WUI（混合和界面）地区发生野火的情况。我们发现，界面WUI包含50%的建筑物被野火摧毁，而混合WUI只包含32%。各类别中被火灾摧毁的建筑物的比例相似，但最高的界面WUI地区（15.6%）。我们的研究结果表明，界面WUI是大多数建筑物被摧毁在加州，尽管较少的荒地燃料。为加州和其他地方的界面WUI定制的模型、缓解措施和法规的持续发展将补充先前对混合WUI的关注。
Globally, and in the US, wildfires pose increasing risk to people and their homes. Wildfire management assumes that buildings burn primarily in the wildland-urban interface (WUI), where homes are either ignited directly (especially in intermix WUI areas, where houses and wildland fuels intermingle), or via firebrands, the main threat to buildings in the interface WUI (areas with minimal wildland fuel, yet close to dense wildland vegetation). However, even urban areas can succumb to wildfires. We examined where wildfire damages occur among urban, rural and WUI (intermix and interface) areas for approximately three decades in California (1985-2013). We found that interface WUI contained 50% of buildings destroyed by wildfire, whereas intermix WUI contained only 32%. The proportion of buildings destroyed by fires among classes was similar, though highest in interface WUI areas (15.6%). Our results demonstrate that the interface WUI is where most buildings were destroyed in California, despite less wildland fuel. Continued advancement of models, mitigation and regulations tailored for the interface WUI, both for California and elsewhere, will complement the prior focus on the intermix WUI.
