项目摘要
Wetlands that dominate the Western Boreal Forest (WBF) are particularly important due to their capacity to store water and carbon. The Boreal zone spans the transition from persistent seasonal ground ice to discontinuous permafrost and is expected to experience unprecedented warming. This warming is likely to cause a hydrological-ecological response, particularly in wetlands. The region is also stressed by increased industrial activity that may exacerbate the effects of climatic variability on wetland sustainability. These disturbances lead to changes in ground ice conditions (including permafrost degradation at the northern extent of this region) and surface cover, which directly affect the tenuous balance between evapotranspiration and precipitation, thereby posing serious challenges for sustainable water and natural resource management. The strong influence of ground ice on wetlands in the Boreal zone likely makes these ecosystems particularly susceptible to "hot" positive feedbacks, where disturbance may cause rapid non-linear responses in local climate, hydrology and biota. However, there remains a lack of understanding of the rates of frost layer degradation and the effects on surface cover and hydrological-ecological processes.
西部北方森林(WBF)中占主导地位的湿地因其储存水和碳的能力而特别重要。北方地带跨越了从持续的季节性地面冰到不连续的永久冻土的过渡,预计将经历前所未有的变暖。这种变暖可能会引起水文生态反应,特别是在湿地。该区域还受到工业活动增加的压力,这可能加剧气候多变性对湿地可持续性的影响。这些扰动导致地下冰状况(包括该区域北方地区的永久冻土退化)和地表覆盖发生变化,直接影响到蒸散量和降水量之间的脆弱平衡,从而对可持续的水和自然资源管理构成严重挑战。地面冰对北方带湿地的强烈影响可能使这些生态系统特别容易受到“热”正反馈的影响,在这种情况下,扰动可能会导致当地气候、水文和生物区系的快速非线性反应。 然而,人们对霜层退化的速度以及对地表覆盖和水文生态过程的影响仍然缺乏了解。
