摘要：泰加林是世界上最大的陆地生物群落,占世界森林覆盖率的29%,对调节全球气候有着至关重要的作用。由于泰加林内枯枝落叶分解速率极低,经过多年的积累后,地表的枯枝落叶层和腐殖质层很厚,发生森林火灾的风险高。火干扰是泰加林生态系统最主要的自然干扰,也是塑造森林群落结构和动态特征最强大的生态因子。火干扰后泰加林的过火面积、林分演替以及碳释放量的研究,是在预期的全球变暖情况下推断火后林分演替趋势的基础步骤。本文综述了位于西伯利亚的泰加林由野火所引起的森林结构与功能的变化和火干扰对泰加林区碳释放量的影响,同时分析了西伯利亚泰加林森林与居住区交界处的抗火性策略,可以为全球气候变暖趋势下研究火干扰对中西伯利亚泰加林林分演替以及碳的释放量提供参考。
The Taiga forest is the world's largest terrestrial biome,accounting for 29%of the world's forest cover and playing a crucial role in regulating global climate.Due to the very low decomposition rate of leaf litter in Taiga Forest,after years of accumulation,the surface of leaf litter and humus layer is very thick,and the risk of forest fire is high.Fire is the main disturbance in the Taiga forest regions,and it is also the most powerful ecological factor shaping forest community structure and dynamic characteristics.The burned area,forest succession and carbon release of Taiga forest after fire is a fundamental step to extrapolate stand replacement trends in the context of expected global warming.In this paper,we reviewed the changes in forest structure and function caused by wildfires and the effects of fire disturbance on carbon emission in Siberia Taiga forest.At the same time,we analyzed the strategies of fire resistance at the forest-residential junction of the Siberian Taiga forest.This study could provide a reference for the forest succession and carbon emission from fire disturbance in central Siberia under the global warming trend.
