• The results showed that forests, grasslands, irrigated crops, and rain-fed crops could be added by 10.23%, 11.65%, 7.67%, and 9.49%, respectively. Overloaded vegetation occurs more frequently in this region's western and north-central parts, mainly due to the water deficit. Among them, overloading was most severe in northwestern grasslands, presumably because these overloaded areas are in the hyperarid zones. The higher revegetation potential is mainly found in grasslands and forests, mostly in the central and southern places (Fig.\ref{416579}a,\ref{416579}b), which is more related to water surpluses.
