英文摘要	Karst rocky desertification (KRD) has become the most serious ecological disaster in the southwest of China and is a major obstacle to the sustainable development of the karst region in the southwest. Remarkably, scientific understanding of the spatial-temporal evolution of rocky desertification and the corresponding driving mechanism is the primary prerequisite crucial to controlling rocky desertification. Hence, the typical rocky desertification area of Qujing City, located in the upper reaches of the Yangtze River, was selected as the research object. On the basis of the Google Earth Engine (GEE) cloud platform and decision tree classification, the spatial-temporal evolution process of rocky desertification in Qujing City from 1990 to 2020 was investigated, and the driving factors of rocky desertification were explored in terms of the natural environment and socio-economic aspects. Consequently, over this period, the area of rocky desertification had decreased by 1728.38 km(2), while the no rocky desertification area had increased by 1936.61 km(2). Notably, the major driving factors of rocky desertification were fractional vegetation cover (FVC) (q = 0.41), land use type (q = 0.26), slope (q = 0.21), and land reclamation rate (q = 0.21). Typically, rocky desertification is likely to occur in areas with moderate or low FVC (<0.7), a low slope (0-8 degrees) or high slope (35 degrees-80 degrees), a land type of cultivated-land or grassland, and a land reclamation rate of 10-70%. In addition, all two-factor interactions acted as drivers that exacerbate rocky desertification. Furthermore, FVC boolean AND slope (q = 0.79) and slope boolean AND land use type (q = 0.56) were two interacting drivers that promote rocky desertification strongly.
