Wind erosion is one of the primary reasons leading to land degration and causing environmental problems in the world. In the paper, research on occurrence mechanism and control technology of wind erosion in agricultural lands is reviewed. It was put forward that planting trees, controlling the degradation of grassland and developing conservation tillage were the effective measures on reducing wind erosion. At present, as the problem of soil wind erosion and cropland desertification becomes very serious in China, more work should be done on protecting the cropland, planting trees and grasses. Also a lot of related policies should be formulated and fund from the governments should be put into in order to popularize the conservation tillage in the whole country.
