Abstract:: Refer to the vegetation restoration technology used in the sand cutting sites of the highway in Otindag Sandy Land, this paper provide an optimal allocation and technology mode of vegetation restoration in sand cutting sites of highway-gravel barrier & low rhombus reed sand-barrier & high salix sand-barrier & Pinus sylvestris var. mongolica forestation. The study showed that the survival rate and preservation rate have increased 30 percent and 35 percent to comparing plots; coverage of vegetation 5 times more than barren sand, composing of vegetation tended to more diversified and stabilized. The wind speed decrease rate was 14.61 percent of barren ones, sand transport rate have reduced 91.7 percent, the roughness of surface have increased 38.86 times than original one. The mode was not only greatly weakening the intensity of wind near surface, but also reduced the sand transport, and improved the soil characters.
