摘  要：
北方针叶林土壤是一个重要的碳库,其林床蓄积了大量养分。火干扰是北方针叶林生态系统结构和功能的重要调节器,能够快速有效地改变林下环境。本文综述了林火加热土壤和火烧残留物对土壤物理化学和生物学性质的影响。最近的研究表明燃烧显著改变了土壤性质和养分循环,火后残留物(灰分和黑炭)仍继续影响土壤性质,并能促进土壤养分循环。此外,林火还显著改变了土壤微生物的生物量及其组成。火对土壤系统的影响,进而会影响立地生产力和生物多样性。因此,探讨火干扰对北方针叶林林下土壤性质的影响,对于揭示火后植被更新的机制和森林管理具有重要意义。

摘  要：
Soil in boreal forests is an important carbon pool, and its forest floor accumulates large amounts of nutrient. Fire disturbance is an important modifier of ecosystems structure and functions in boreal forests, rapidly and effectively altering soil environment. We review the effects of soil heating during fires and fire residues on soil physical, chemical and biological properties. Recent studies have demonstrated that burning can significantly alter soil properties and biogeochemical processes, and post-fire residuals(ash and charcoal) can continue to influence these properties and stimulate nutrients cycling. In addition, fire alters both quantity and specific composition of microorganisms. The effects of fire on soil ecosystems can further influence site productivity and biological diversity. Therefore, understanding the effects of fire disturbance on soil properties in boreal forests is important for disclosing the mechanisms of post-fire plant regeneration and managing forests.
