According to the annual average total runoff of the Qaidam Basin in the Qinghai water resources bulletin, after deducting the glacier recharge, the Z value is determined by comparing the simulation results of the annual water production of the Qaidam Basin from 1980 to 2018. Through error calculation, it is found that the simulation results of the invest model for water production are relatively accurate, and the relative error is less than 5%.
