摘要
The results from a series of 3- to 6-year simulations of the climatic impacts of tropical deforestation using a version of the NCAR Community Climate Model (CCM 1-Oz) indicate considerable sensitivity to the specification of the vegetation and soil that replaces the tropical forest. The simulations, which encompass landscapes from forest, through grass with some trees, grass-only, no vegetation with forest soils, to a devastated terrain, suggest that the predicted climate change depends about equally on at least three factors: (i) the global model and its large-scale circulation sensitivity, (ii) the length of the model simulation, and (iii) the nature of the prescribed land-use change, particularly the relative magnitudes of the changes (forested to deforested) in albedo and vegetation roughness length.
