[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.
