摘要

据观察，2017年葡萄牙特大火灾的蔓延被当地的原始森林斑块所遏制。在这里，我们提出了火灾行为的空间模拟情景，以评估在工业园区(IZs)周围的荒地-城市界面(WUI)地区，在极端野火条件下，原始森林覆盖是否减轻了火灾的蔓延。研究结果表明，阔叶林覆盖可使保护区周边火线强度和蔓延速度平均分别降低20倍和8倍。因此，我们的研究结果支持讨论葡萄牙森林管理以更好地预防WUI火灾的必要性。

Is native forest an alternative to prevent wildfire in the WUI in Central Portugal?

he expansion of the 2017 mega-fires in Portugal was observed to be locally halted by native forest patches. Here we present spatial simulation scenarios of fire behaviour to assess whether native forest cover mitigates fire spread during extreme wildfire conditions in wildland-urban interface (WUI) areas around Industrial Zones (IZs). Our results suggest that broadleaved forest cover can reduce fireline intensity and rate of spread around IZs up to 20 and 8 times, respectively, on average. Thus, our results support the need to discuss forest management in Portugal to better prevent WUI fires.
