Desertification difference index (DDI) was used to evaluate the degree of desertification in the Corridor. Based on Normalized Difference Vegetation Index (NDVI) and Albedo, we established the Albedo-NDVI space and a DDI formula through negative correlation between Albedo and NDVI. Based on DDI, we built the dataset of desert distributions along the China-Pakistan Economic Corridor during 2000 – 2017.
