Abstract:: Improving our knowledge about the characteristics of wind erosion dust in different land use types is crucial to understand the wind erosion process and provide the data for improvement of ecological environment at the regional scale. In this study, the quantity, particle size, carbon and nitrogen of wind erosion dust were measured in five land use types(fruit mulberry, Chinese dwarfcherry, grape, no-tillage with stubble, ploughed up)during winter fallow(November to next February)and spring preparation period(March to May)in Huailai County. We found that the quality of wind erosion dust in Chinese dwarfcherry and plough treatments decreased with the increase of height, while it showed no unified patterns in fruit mulberry, grape, and no-tillage with stubble treatments. Our results also showed that the sediment flux in spring preparation period was higher than that in the winter fallow period. In addition, the particle size of wind erosion dust ranged from 500～2 μm during winter fallow period, and ranged from 250～2 μm during the spring preparation period. Furthermore, the carbon and nitrogen contents of wind erosion dust during winter fallow period were higher than those during spring preparation period. Wind erosion quality, carbon and nitrogen contents, particle sizes are influenced by the land use types and human activities. It is applicable to reduce near-surface wind speed, intercept wind sand by building grass hedge and adjusting the layout of different land use types.
