摘要：

The article focuses on the effect of loss of forest humus on fire-derived charcoal. Boreal forests are considered as significant global sources or sinks of carbon (C). Fire converts plant biomass into forms of black carbon that are resistant to microbial attack and persist in the soil for thousands of years. It has been suggested that black C can be a relevant long-term C sink that may help in releasing human-induces carbon dioxide to the atmosphere. Study shows that fire often causes substantial losses of ecosystem C.
