A series of field observations of sand blowing on different utilizing land patterns in Beijing outskirts was finished during the winter of 2005 and the spring of 2006.The result showed:(1) In three patterns of shelterbelt

the roughness length of arbor-shrub-grass compound land was the most than the roughness length of the others(sparse woodland and woodland-grass compound land)

the effect of weaken wind speed and reduced soil erosion was the significant.(2) In farmland

the roughness length of fruit-cabbage intercrop land was the most than that of the other farmland patterns

and the effect of weaken wind speed was the best.(3) The effect of no-tillage land reduced soil erosion was the significant.(4) In three patterns of shelterbelt

the effect of arbor-shrub-grass compound land was the best

and no-tillage and fruit-cabbage intercrop land were better in farmland on the surface soil erosion.
