    The diachronic land use analysis, performed by processing the sensor data , is based on the 10 and 30 year change maps. The dynamics of the vegeta t io n is followed by the application of the NDVI. The gradual and regressive changes in the components of land use reached the rates of 44.78% and 29.21% respectively. The most reduced surfaces are the forest massifs, the steppe area and to a les ser extent th e waters of the saline surfaces (dayet). Cereal crops, urban and mineral areas, on the other hand, have increased in area to the detriment of the natural plant cover. The stability of the studied area recorded only a rate of 26.01%. This rate r epresente d o nly ¼ of the area of the south of Tlemcen region.
