| Summary: | Mapping the spatial variability of soil salinity in an endorheic region (Gadaine, North-Eastern Algeria). The process of soil salinization is one of the causes of desertification in Algeria and in the world, according to the figures (FAO, 2005), where it found that 500 000 ha/year of soils belong to them. In eastern Algeria, the endorheic areas of Gadaine plain present an expanding soil salinization taking the form of a generalized phenomenon. The environmental and effective management requires a mapping of the spatial distribution of this geochemical phenomenon. To explore the spatial variability of soil salinity in this area, we used the approach of geostatistical mapping (ordinary kriging) to generate a map of salinity. 258 samples were taken laterally from the field, in order to determine the electrical conductivity (EC) of the soil. Results show that, the salinity affects a large part of the study area and also show the influence of the natural drainage on the spatial distribution. The use of database associated with digital mapping has helped to ensure the most accurate results. |
