Spatiotemporal dynamic evolution and driving factors of desertification in the Mu Us Sandy Land in 30 years

Abstract The Mu Us Sandy Land is located in the middle of the farming pastoral ecotone of northern China. The direction of the development of desertification has a direct impact on the economy and development of the northern region. Six remote sensing images acquired during 1990–2017 served as data...
