The intense degradation for this fragile medium (stranding wind erosion, overgrazing, clearing, salinisation, ...) inducing the turning into a desertification require a better comprehension in order to see how to fight against this plague and to adapt an adequate installation to him. Thus, this work lies within the scope of the follow-up of the phenomenon of the turning into a desertification on a space with the heart of the high Oranian southern steppe plains, in fact the area of Mecheria. Techniques of numerical cartography, since the satellite image processing until the geographic information systems (SIG) for the realization of the charts sets of themes, being able to highlight this calamity. The use of the approaches based on the exploitation of the satellite data multi dates (1998 & 2004) of the sensor Thematic Mapper (TM) of Landsat 5 permitted us to obtain a gathering of an interpretative photo maps and vegetation index which, in their turn, helped us to see the changes arrived in the medium, copiously regressive that progressive.
