Aeolian Movement Characteristics over Different Underlying Surfaces in Mu Us Sandy Land
|
Abstract:
Aeolian movement characteristics over different underlying surfaces in Mu Us Sandy Land was researched based on field measurement.The results showed that wind profile over flat drifting sand followed logarithmical rule against height.Under similar wind-speed,the sediment discharge intensity within 0~60 cm successively distributed as mobile dune top>flat drifting sand>semi-mobile dune top>bare loess flat-topped ridge>dumped loess cropland land>maize stubble land>semi-mobile dune top.At given vegetation cover...
