[Objective] Research was conducted on understory litter and soil hydrological function for artificial forests in the forest protection station in the eastern section of the Kubuqi Desert. The comprehensive weight value of various indicators of the artificial forests in this area were scientifically calculated, and the hydrological effect and water conservation function of artificial forest litter and soil were determined in order to provide theoretical guidance for the directional tending of returning sand to forest in this area and related sandy areas. [Methods] Five common types of artificial shelterbelts were used in the Ordos afforestation station in the Kubuqi Desert. The water-holding capacity of litter and soil were determined using field measurements and the indoor immersion method, and the water conservation function of each forest was assessed using a combination of the analytic hierarchy process (AHP) and the entropy-weight method (EWM). [Results] ① The litter thickness in each stand ranged from 6.
