野火是泥炭地环境的一个常见特征，但通常不考虑这些野火的碳平衡，这些野火中产生的难熔黑碳可能是碳积累的重要补充，并减轻火灾期间生物量的损失。这项研究调查了沼泽野火期间的生物量和碳损失。结合现场数据、实验室测量值和文献值计算地上碳储量的变化。结果表明，原始地上生物量中大约 14% 的碳在燃烧后仍留在现场。黑碳产量约为6 gC m(-2)，占生物量损失的4.3%。生物质和黑碳的存留可能有助于减少火灾期间碳的损失。 (C) 2010 Elsevier Ltd. 保留所有权利。
Wildfires are a common feature of peatland environments, but the carbon balance of these wildfires is often not considered and the production of refractory black carbon in these wildfires could be an important addition to carbon accumulation and mitigate losses of biomass during the fire. This study investigates the biomass and carbon losses during a moorland wildfire. Changes in above-ground carbon stocks were calculated using a combination of field data, laboratory measurements and literature values. The results show that approximately 14% of the carbon in the original above-ground biomass remained on the site after the burn. Black carbon production was approximately 6 gC m(-2) which constituted 4.3% of the biomass lost. The survival of biomass and black carbon may help to mitigate the loss of carbon during the fire.
