项目摘要

Warming and drying trends in western Canada’s Boreal region have increased due to climate warming. This has caused a marked shift in the area burned by wildfire over the last 10 years, doubling that of the 1970’s. The area burned by wildfire is expected to increase over the next century due to continued warming and longer fire seasons. While fires are a natural part of ecosystem succession, they also pose significant threats to the economic and social stability of urban and industrial areas. Drying wetlands may provide additional fuel for wildfires, potentially having negative human health implications as a result of lingering air pollution. Yet the vulnerability of wetlands to wildfire is difficult to quantify, especially over broad and often remote regions, but is required for better understanding of the climatic, ecological and social consequences of wildfires now and in the future. My research program, FISIL, will improve understanding of vegetation structural, topographic and hydrological drivers of forest fire fuel consumption and post-fire vegetation regeneration trajectories within wetland to forest transitional zones that have undergone recent natural or anthropogenic change. Wetland ground cover and short vegetation canopies are of particular concern because their impacts on fire severity are not well understood, and are poorly parameterised in operational fire prediction models.

由于气候变暖，加拿大西部北方地区的变暖和干燥趋势增加了。在过去的10年中，这引起了野火烧毁的地区的显着转变，使1970年代的变化翻了一番。由于继续变暖和更长的火灾季节，野火燃烧的地区预计将在下一世纪增加。尽管大火是生态系统成功的自然组成部分，但它们也对城市和工业地区的经济和社会稳定构成了重大威胁。干燥的湿地可能会为野火提供额外的燃料，由于空气污染挥之不去，可能对人类健康产生负面影响。然而，很难量化湿地对野火的脆弱性，尤其是在广阔的偏远地区，但要更好地理解现在和将来的野火的气候，生态和社会后果所必需的。我的研究计划FISIL将提高人们对森林火灾燃料消耗的植被结构，地形和液压驱动因素以及湿地内植被后再生轨迹的理解，这些轨迹是森林过渡区，这些森林过渡区具有近期自然或人为变化的原因。湿地的地面覆盖物和短植被檐篷特别令人关注，因为它们对火灾严重程度的影响尚不清楚，并且在操作火灾预测模型中参数较差。我的
