Résumé
The Mediterranean desert west of Alexandria (Mariut) is one of the arid regions which has a long history of intensive land-use. The evaluation of the diversity of its plant resources and the effect of land-use on such diversity is the main objective of the present study. In the present study, species diversity was assessed by several indices. The simplest index is merely the number of species in a community (or habitat) and is called” species richness”. Taxonomic diversity was calculated at both genus and family levels on the same lines as species richness. Other diversity measures take into account two factors, species richness and evenness (sometimes known as equitability), that is how equally the species are. Species abundance models were also used to describe the distribution of species
