Effects of climate warming on carbon sink of forest ecosystems:Mechanisms,methods,and progresses
Forests are important carbon sinks,absorbing about 33％of the carbon dioxide released from fossil fuel combustion each year.Since 1850,global temperature has increased by 1.1 ℃,and in the future,global tempera-tures are likely to rise to 2.7-4.8 ℃.However,there are controversies over the direction,degree,and mechanisms of the impact of global warming on forest carbon sequestration,which seriously affects the prediction of future global climate change and the policy-making of government carbon emission control.This article summarizes the mecha-nisms,research methods,and main progresses of the impact of global warming on the carbon sink capacity and processes of forest ecosystems.In addition,we propose future priority research areas.
