摘要：The study deals with the implementation of spatial tools to analyze the socio-ecological information that allows developing strategic orientations linked to the spatial planning of Oued Beht watershed. Thus, the obtained interactive mode is based on a spatial autocorrelation approach and focuses on the geoprocessing of statistical information to delimit areas that require priority planning and to provide significant visual results for the manager. The spatial structure modelling obtained, as z-score, expresses the interactions between erosion hazard and boundary conditions which will be modified by the proposed action plan. The results are synthesized in decisional maps using Hot Spots Analysis. Indeed, the integration of the priority areas in the obtained geographic information system (GIS) offer an excellent tool for monitoring soil degradation and erosion control development adapted to local conditions. The socio-ecological vulnerability characterizes 32% of watershed and the priority areas are generally occupied by soils with strong erosion risks. Specifically, the final development map is used to highlight actions to be taken in areas requiring priority management. Therefore, the spatial analysis of all results led to define efficient biological actions for erosion control such as fruit trees plantation, reforestation in degraded areas; and to identify mechanical measures (terracing, benches, ditches and correcting ravines) in order to mitigate the negative impacts of water and soil losses
