Abstract

Using potential natural vegetation (PNV) and satellite-based land use data, the AA. determined the possible maximum distribution extent of forest cover in the absence of human disturbance. Subsequently, topography and climate factors were selected to assess the suitability of land for cultivation. Finally, a historical forest area allocation model was devised on the basis of the suitability of land for cultivation. As a case study, the AA. used the historical forest area allocation model to reconstruct forest cover for 1780 and 1940 in Northeast China with a 10-km resolution. To validate the model, the AA. compared satellite-based forest cover data with the reconstruction for 2000. The results demonstrated that the provincial forest area could be transformed into forest cover maps well using the model
