The study of plant associations in salt marshes of the Mouteh Refuge, Delijan

Mouteh Refuge covers an area of 200000 hectars located in the northwest of Meymeh and southwest of Delijan. In this study، the vegetation of salt marshes in Mouteh Refuge was studied، using the Braun-Blanquet method. Phytosociological data were analysed by analyse factorielle des correspondances (AFC) and classification ascendant hierarchique (CAH) methods، using the Anaphyto software. In general، 17 plant associations were determined in the area. Some of physical and chemical soil features of plant association’s habitats were measured. Principal component analysis (PCA) was used to analyze the soil data. The results showed that the plant association’s distribution was mainly related to EC، Na، Ca، Mg، Cl، SO4، HCO3- and to the texture of soil.
