The systematic sampl ing of near surface wind-blown sediment and corresponding upper soil in Bashang region

Hebei pro vince is co nducted.The result showed that the quantity of wind-blown sediment decreased exponent ially with the incr easing heig ht above ground level.The content of f iner part icles( ≤0. 25mm)

or ganic matter and plant nutrient incresed significantly in wind-blow n sediment in comparison with that of corresponding upper soil surface. As the sample size increased

the percentage of sand increased but the silt and clay decreased

and the content of organic matter and plant nut rient decreased. However

the percentage of finer particles ( silt and clay ) and the content of or ganic matter and nutrient increased with the increasing height abov e soil sur face

it indicates that the amount of fine particles and plant nut rient lost f rom soil during higher er osive w ind environment . In addition

tillage methods af fect the soil wind erosion through changing surface properties and then influence the physical and chemical characterist ics of wind-blown sedment .
