MAPPING POTENTIAL OF MANGROVE FORESTS BASED ON SITE DEMANDS (GEOMO RPHOLOGICAL FACTORS AND PHYSICOCHEMICAL CHARACTERISTICS OF SOIL AND WATER)Kh. Mirakhorlou, S. Teimouri and M. Abadeh
Mangrove forests as tropical ecosystems index are considered in three universal environmental agreements, the Convention of Wetlands, Biodiversity and World Heritage. This study was conducted to determine potential areas for developing mangrove forests by Avicennia marina and Rhizophora mucronata in the northern coast of Persian Gulf. To study geomorphological factors, landuse and land form maps extracted from IRS satellite images (LISS-III) from May 2014. From landuse, forest, Unvegetated Wetlands, Tidal Flat and Wetlands and from landform Delta Plain, Estuary, Creek, Mud Flat, Tidal Flat and River were extracted. By overlaying these maps and field surveys, the overlaps were considered as potential area of Mangrove forests. Finally, Development potential area were estimated 130994 hectares. Sites of Bandar - e - Khamir, Gheshm and Mlgnzeh were selected as a control area to study the site demands (physicochemical characteristic of soil and water). Soil and water of the area with forest regeneration, forest without regeneration and non forest, were sampled. The results showed that EC, PH, Na+ and silt factors in the soil of forest with regeneration and without regeneration is significantly ( p< 5% ) lower than the nonforest, and O.C, P (AV) factors and sand is significantly (p< 5%) higher. In the water samples, none of EC, pH, Ca ++, Mg ++, Na + and K + parameters showed significant difference.
