Managing clear-cutting forest for carbon sequestration in living biomass: A case study in subtropical of china

摘要

Forest reconstruction was regarded as a measure of carbon sequestration and climate change mitigation. The carbon stocks in living biomass were compared between artificial measures promoting regeneration of Castanopsis carlesii (ARC) and two adjacent plantations of Cunninghamia lanceolata (CFP) and Pinus massoniana (PMP) and natural primary forest (NPF). The mean carbon stocks were about 150.1 Mg ha~(-1) in ARC and 90.6 Mg ha~(-1) in CFP and 83.9 Mg ha"1 in PMP. The results primarily showed that the carbon stock in artificial measures promoting regeneration were higher than that two plantations. Carbon stocks in the all reconstruction of forests were all significantly lower than those of NPF (186.9 Mg ha~(-1)), which also implies they still have a carbon sink increment potential.
