[Objective] The variation characteristics of sediment transport for different specifications of gauze sand barriers in spring, summer and autumn were obserred continuously in order to provide a scientific basis for further evaluation of the sand-fixing effect of gauze sand barriers.[Methods] Field positioning and regular observation methods were used to determine the amount of sediment transport for gauze sand barriers in different seasons in the Ulanbuh Desert.[Results] The 2 m×2 m, 3 m×3 m, 3 m×4 m, and 4 m×4 m gauze sand barriers were set to intercept wind and sand flow, and the effects increased as grid-spacing became smaller. Sediment load changed with height above the soil surface in an exponential relationship in all three seasons. The amount of sediment transported by the northwest wind was more than the amount transported by the southeast wind. The amount of sediment transported in spring was more than the amount transported in summer and autumn. Compared with the control, the net sediment transport intercepted in the 0-60 cm height range was reduced 85.98% by the 3 m×4 m gauze sand barrier in spring, and the net sediment transport in this height range was reduced 79.56% in summer and autumn.[Conclusion] Sediment transport of the gauze sand barrier was mainly concentrated in the 20 cm height range above the ground surface. As the size of the gauze sand barrier increased, its ability to reduce the amount of sediment transport decreased. Gauze sand barriers can be set to effectively reduce the hazards of wind-sand flows.
