| 英文摘要 | Despite the need for climate change mitigation and altered forest management practices, little is known about the impacts of silvicultural practices such as partial-cuts and clear-cuts on forest ecosystem carbon (C) dynamics. Specifically, the effect of these two overstory treatments on C pools other than the aboveground biomass of trees remains poorly understood. Here, C stocks were estimated for a northern temperate mixed forest located in eastern Que ' bec, Canada, five years after clear-cutting and partial-cutting, either with or without a brushing treatment to control the competing vegetation. The biomass of the aboveground vegetation (trees, saplings, understory), litter and woody debris (coarse, small, fine), as well as the roots (diameter <= 1.5 cm) was evaluated. Additionally, soil C pools up to a depth of 35 cm of the mineral soil were assessed. Total ecosystem C stocks were influenced by the overstory treatments reflecting harvest intensities. Although the belowground C pools were major contributors to total ecosystem C stocks, silvicultural treatments only influenced forest floor and aboveground C stocks. However, assessments like the one presented here capture contemporary C stocks, which highlights the need for monitoring to build suitable forest ecosystem C models and to understand long-term C dynamics. |
