📄 Abstract（原文）
Introduction European forests have provided a persistent carbon (C) sink equivalent to around 10% of current C emissions over the past few decades. While this sink is often considered natural, the dynamic conditions that sustain it have remained unexplored, raising questions about its long-term stability. The cumulative intensity of this sink since the onset of C emissions also remains critically undocumented, due to the lack of a historical monitoring of forest growing stock (GS) since European forest transitions. These questions were addressed for the temperate forests of France, which underwent a forest transition in the mid-19th century. Methods We developed a forest densification model guided by a 40-year contemporary time series of forest GS established from the national forest inventory (NFI), and century-old areal statistics. Results Simulations identified a singular convex GS densification model over 150 years, and an initial GS density of 25 m 3 /ha, supporting reports of historical forest depletion. GS as estimated for three historical statistics required low-density (15–30%) contemporary forest analogs to match the simulated trajectories, translating into a 5-fold increase in GS over the last century, and a minimum 10-fold increase since 1850. The coincidental and favorable roles of continuous forest extension, management extensification and environmental growth changes in this dramatic biomass increase were evidenced. Discussion Rescaled to aerial wood carbon, this in situ accumulation represented 10.5% of the cumulated fossil C emissions, questioning the viability of the forest dynamics to be maintained, were forests to remain a prioritized option for climate change mitigation in the future.
