  • 摘要:The highlands of Eastern Algeria are characterized by an endorheism namely a local base level that does not allow the water system to get to the sea. The Area of chotts and sabkhas of Gadain region can be considered as an area of degradation lands due to the dynamics of sabkhas and chotts that are localized and installed on large areas on one hand and accelerated anthropogenic pressure on the other hand. This dynamic often presents special large extension, this study requires accurate and geo localized information's. The analysis of the dynamics of chotts and sabkhas based on medium resolution satellite images on two different dates (Landsat TM 1987 and TM 2009) specializes (mapping) and evaluates this dynamic. The comparison of the results provides an overview of the affected areas by the dynamics of sabkhas and chotts and their direction for 22 years.
