Description :
The AA. first select and quantify the major drivers of the historical cropland distribution, and conduct an empirical model to pixelize the historical cropland data. In a case study, this model is used to reconstruct the pixelized cropland data based on provincial records in 1820. They then statistically test the results with the prefectural records in 1820 to check the efficiency of the model. The gridding model conducted in this study can well introduce the numerous cropland data into the climate model or the other integrated global change models.
