Although Coastal regions have occupied less than 15% of the earth surface, but (they invalue) 60% of the world population. These regions defined as eco-tone have more susceptibility than other terrestrial ecosystems. Pressure increase on these regions can decrease the quality of habitats and even ssensitive them. This study was done according to the national strategic plans of Irans fishery and environment to achieve general classification and encoding the coastal regions ecologically. It was conducted in 2010 based on coastal and marine ecological classification standard (CMECS) criteria as well as library and field studies, satellite photographs analysis, spatial coverage maps and two groups of data including surface geo-morphological components and bio-covering components. Eventually, the habitats were encoded. The results of the assessments determined the habitat adversity of the studied region (Mazandaran province) was bound to 4 types comprising coastal and sandy as the dominant types and estuary (seasonal and permanent rivers) and swamp ones. Environmental changes (season) could be identifiable and distinguishable for two fluctuation periods of spring-summer and fall winter.
