Abstract:: The morphology and sediment characteristics of nebkhas on slopes were studied by means of field observation and sampling in Bashang region, Hebei Province. The results show that:(1) from the top to the foot of the investigated hills, the morphology parameters of nebkhas gradually increase, and the morphology parameters of nebkhas for the windward slope is greater than those for the leeward slope; (2) from the foot to the top of the investigated hills, the percentage of the coarse grain (diameter >0.1 mm) of the surface sediments of the nebkhas gradually decreases, the percentage of the coarse grain (diameter > 0.1 mm) of the surface sediments in the windward slope is greater than that in the leeward slope; (3) from the foot to the top of the investigated hills, the surface soil moisture and the soil hardness of the nebkhas become greater, and the surface soil moisture and hardness of the windward slope are less than those of the leeward slope; (4) from the foot to the top of the investigated hill, the bulk density becomes less, and the bulk density of the windward slope is greater than that of the leeward slope. In addition to the three main factors of cover, wind strength, and sand, the site condition is an important factor which influences the formation and evolution of nebkhas on slopes.
