Because of the climate changes and the massive clearings, some of the most critical problems that Romania and especially the S-W part of Oltenia are confrunted with are: the desertification and the earth flows. The purpose of the shelter - belts in preventing the effects of the wind and in protecting the agrarian crops and the agrarian production implicitly, can be evaluated by keeping in mind a series of specific determination: soil, climate, wind rate, the quantity of driven sand, wind erosion, soil erosion, agrarian production, density of crop. In this paper it is proven that the best results were obtained when the protection of the agrarian fields was made with the help of the shelter-belts arrays, made so that two shelter-belts encased and directed perpendicular to the dominant wind direction in order to confine an agrarian crop in rotation and, with their accumulated effect, to reduce the wind rate at soil level up to almost zero.
