Table 2.
Scenario design based on critical indicators in the study area.
‘S1’ is the historical land-use demand scenario reflecting land demand growth as a continuation of the historical period. ‘S2’ is the moderate protection scenario in which land demand growth was limited by setting critical indicators of economic and social development. ‘S3’ is the strict protection scenario in which land demand growth was simulated with multiple strict protections in the study area.
Table 3.
Carbon pools of different land-use types in InVEST (units: MgC•ha−1).
‘Ca’ refers to the aboveground biomass. ‘Cb’ refers to the belowground biomass. ‘Cs’ refers to the soil organic carbon. ‘Cd’ refers to the dead organic matter.
