Populouspopulars farmland shelterbelts were afforested by ways of planting and sprout seedling in the Hetao irrigated region. Wind speeds in different sites of shelterbelts were measured and analyzed statistically. Results showed that wind speeds were reduced effectively by Populouspopulars farmland she-lterbelts. Different afforestatio n w ays had no sig nificant difference in w ind-reducing effects. The coefficient of reducing wind was the largest in 2H. In view of w ater consumptio n and costs, afforestation by way of planting is superior to afforestation by way of sprout seedling.
