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%.
