Abstract:Soil wind erosion is a prominent ecological problem in the sustainability of oasis farmland in arid areas, therefore, how to take reasonable protective measures against different farmland units is a key concern in arid areas for a long time. In this paper, five typical land use types of shifting sandy land (SSL), sandy arable land (SAL), clayey arable land (CAL), abandoned grassland (AGL) and stubble land (SL) of oasis in Ulan Buh desert were selected, wind speed, surface erosion and deposition, surface roughness and soil particle size distributions (PSDs) were analyzed. The results showed that fine sand was dominant in soil PSDs of all land use types, and the contents of clay sand and coarse sand were relatively low. Compared with SSL, other land use types effectively increased surface roughness, which were in an order of SL (0.32 cm) > AGL (0.29 cm) > SAL (0.25 cm) > CAL(0.19 cm)> SSL (0.02 cm). The depths of soil erosion were in an order of SSL> SAL> CAL> SL. SL was the slightest in wind erosion degree with a wind erosion depth only of 0.04 cm/d, decreased by 99.03%, 96.83%, 94.29% and 90.24% compared with those of SSL, SAL, CAL and AGL, respectively. Thus, stubble land is an effective measure in preventing and controlling soil wind erosion due to its significant wind-intercepting efficiency.
