    ABSTRACT
    This paper continues the work carried out to determine the influence of soil physico-chemical factors on the spatial distribution of matorrals in the plain from Remchi to Béni-Saf located in the western region of Algeria and on the relationships that soil can have on the diversity of matorrals. On the bioclimatic level, the region is characterized by semi-aridity accentuating the phenomena of thérophysation. Soil analysis was carried out using known methods (Stokes Particle Size Method, Electrometric Method for pH, 1/5 Extract Method for Electrical Conductivity, Bernard Calcium Method for Ca CO3, Anne Method for Organic Carbon). The results confirm the following characteristics: sandy-muddy “Remchi”, sandy “Rachgoun 1 and Rechgoun 2”, not far from Béni-Saf. The low clay content (Remchi: Profile 1: Horizon 1 clays 9%, Profile 2: Horizon 1: Clays 12%, Profile 3: Horizon 1: Clays 16%, Rechgoun Profile 1: Horizon 1: Clays 5%, Profile 3: Horizon 1: 5% clays and Horizon 2: 6% clays) leads to poor structural stability and degradation of the soil surface due to visible erosion especially on steep slopes.
