a, Contribution of each region to the total forest area in the eastern United States (%).

b, Contribution of each region to the total C loss of live biomass in the eastern United States (%).

c, Contribution of the forest area of different forests to the total forest area in each region (%).

d, Contribution of the C loss in different forests to the total C loss of live biomass in each region (%).

e, Contribution of the C loss by partial cutting (with a cutting intensity less than 90%) to the total C loss of live biomass in each region (%).

ρC, C loss of live biomass per unit forest area (Mg C ha⁻¹yr⁻¹).
