ABSTRACT: To know the mode of distribution of halophytes species in the western
region of Algeria, it was considered useful to undertake a study based on the
achievement of identified linear. Two areas were considered, Northern Tlemcen (Beni
Saf and Rachgoun) and Northwest Oran (Sabkha). The trend of climate aridity
which is more pronounced in the study area may have influences on floristic
halophytes. The study of the floristic composition showed the importance of
indicator halophitisation species such as Atriplex halimus, Tamarix gallica, Salicornia
fruticosa, Arthrocnemum glaucum and was accompanied by
various therophytes such as Sinapis arvensis, Erodium moschatum, Malva sylvestris and Plantago
lagopus. ANOVA (analysis of variance) has highlighted the factors that
influence the spatial distribution of some halophytes species at five stations
studied; some are dispersed aggregates (Tamarix gallica, Suaeda fruticosa) with a
coefficient of variation (Cv) greater than 10%; others are regularly dispersed
(Atriplex halimus) with a coefficient of variation (Cv) less than 10%.
