[Objective] The soil physical and chemical properties of Caragana Nebkhas were analyzed in different slope position and slope direction at the he Bashang area of Hebei Province in order to keep the slope eco-environment stabile . [Methods] Investigation data of 638 nebkhass and assay data of 86 soil samples were analyzed by geo-statistics. [Results] From the top to the foot of the investigated hills, contents of coarse sand, medium sand and fine sand and pH value gradually decreased, whereas, contents of clay, silt, organic matter, total N and total P showed an increased trend. Soil particle composition was different for slope wind exposure, the contents of coarse sand, medium sand and fine sand in the windward slope of nebkhas were greater than the corresponding values in the leeward slope; Comparatively, contents of very fine sand and silt were less than that in the leeward slope. Soil nutrients(organic matter, total N and total P content) in the foot of windward slope were greater than that in the foot of leeward slope; However, in the middle and top of the windward slope were less than the corresponding values of the leeward slope. pH value had a reverse trend. [Conclusion] Soil properties of nabkhas are different in different slope positions and directions resulted from wind-involved pedogenesis.
