摘要

The Global Wind Action System Saharo-Sahelian ( SGAE) in the interface soil - atmosphere was defined as a set of currents of sand commanded on one hand by the topography: the mega-obstacles (Eglab, Tassili-Hoggar, Tibesti Ennedi, Djebel Marra, Aier, Adrar des Ifoghas), by the fluviatiles paleo-deposits and the winds: Harmattan mainly, on the other hand (Mainguet and Guy,1975; Mainguet, Canon, Chemin, 1980; Mainguet, Dumay, 1995) Along these currents alternate areas of departure and areas of deposits (ergs) connected among them by areas of transit. This work describes what we agree to call the continental terminus Mauritano-Senagalian of the Global Wind Action System. After a synthetic description of the SGAE and the regional sedimentary budgets, a diachronic study of the area of Nouakchott, its pluviometry highlighting the droughts and the increase of the transit notably by the winds of dusts during these dry fluctuations, the vegetation and the sifs, the se'dimentological analysis will confirm the current effects of degradation of the sandy soils by the deflation and the impoverishment in fine particles and in organic matter.
