2009 年 1 月和 2 月分两个阶段影响澳大利亚墨尔本的极端热浪造成的影响非常严重，分别造成 374 人（高温）和 173 人（丛林火灾）死亡。虽然政策和学术领域已经详细讨论了人类健康问题，但对城市基础设施的不利影响却很少受到关注。基于参与性参与者研究的对该事件的分析表明，不同基础设施类型所受到的影响不成比例。对于水、电信和机场来说，影响相对较小，对铁路运输和公路（以及较小程度上的海港）的影响中等，而研究结果表明，电力部门是最脆弱的。本文重点关注受影响最严重的行业：电力、铁路和公路运输。评论指出了高温事件的直接和间接影响，包括相关的级联效应，并考虑了事件前后的实际和潜在的适应反应。最后，作者反思了热浪对城市复原力的影响，强调将城市环境理解为一个复杂且相互关联的系统的至关重要性。
The impact of the extreme heat wave that affected Melbourne, Australia, in two distinct phases in January and February 2009 was severe, with 374 (heat) and 173 (bushfire) excess deaths. Whilst the human health issues have been covered in detail in policy and academic arenas, much less attention has been paid to the adverse impacts on urban infrastructure. Analysis of this event, underpinned by participatory actor-based research, has shown that the impacts were experienced disproportionately across different infrastructure types. For water, telecommunications and airports, the impacts were relatively minor and the impact on rail transport and roads (and to a lesser extent, seaports) was of moderate significance, whereas research findings indicate that the electricity sector was found to be the most vulnerable. This paper focuses on the sectors that were worst impacted: electricity, rail and road transport. Commentary identifies the direct and indirect impacts of the heat event, including associated cascading effects, as well as considering actual and potential adaptation responses both before and after the event. Concluding, the authors reflect on the implications of the heat wave for urban resilience, emphasising the crucial importance of understanding the urban environment as a complex and interconnected system.
