[Objective] The experiments about the new materials of HDPE net and plant fiber net were conducted in Hangjin Banner, Duguitala industrial zone of Hobq Desert, in order to provide theoretical support for the sand-barrier optimization.[Methods] The Met One 014 A/024 A 8 channel anemometers (acquisition instrument CR200 X) were used to observe the 1 min-averaged wind speed at the heights of 20 cm, 80 cm, 150 cm and 200 cm, and the wind profiles under the effects of sand-barriers with different materials, specifications, heights of the checkboard barriers and the highly-set vertical sand barriers were comprised and analyzed.[Results] (1) The high parallel sand-barriers, HDPE and plant fiber net sand-barriers with different specifications all could significantly reduce the surface velocity, they also had good sand-fixing benefit. (2) The vertical wind variation range and regularity measured in the center of the checkboard barriers were found strongly related to the sand-barrier plane specification and the exposing height, no relation was found with the materials. Under the same test specification condition, the higher the exposed height was, the much the velocity was reduced. At the checkboards with the same exposure height, the reducing effect of velocity with small size sand-barrier was more obvious. (3) The determination of the sand-fixing effect of sand-barriers with different specifications should take a full consideration of the influences of the topography position, slope direction, slope gradient and surface conditions. Besides that, it also needs to observe the sediment transport intensity, sand-flow field and other factors of the bare land topography that is not within the measurement zone. All these are essential to obtain the effectiveness of the engineering barrier accurately.[Conclusion] The sand barrier of the new material used in the Hobq desert had excellent effects of reducing velocity, and it has great application prospect in the ecological field.
