Ecological sensitivity of the Persian Gulf coastal region (Case study: Bushehr province)

Abstract

Coastal area sensitivity evaluation is in fact, the evaluation of an extraordinary ecological rich region. This study has been based on established criteria and values. The aim of this sensitivity evaluation has been to give objectivity to the Bushehr Province coastline region, so as to be able to pinpoint areas requiring ecological protection. With this objective, initially, the boundaries of the area under evaluation were first established, based on the findings of the Integrated Coastal Zone Management plan (ICZM). Then, based on these parameters and by
geo-referencing photo mosaic Land Sat Satellite images (2003) and IRS’ (2004) were taken and basic maps of two influential areas were evaluated within the above mentioned limits which included the coastal village boundaries. The coastal line of the area being evaluated (set back line) was 673.62 kms comprising an area of 384,810
hectares. In this research the blueprint of a linear mathematical model was planned according to the Analytic Hierarchy Process method backed by the Arc-GIS Software program. In this model the value of influencing sensitivity factors were not applied in the same manner but by determining weight coefficients, the value and importance of each factor was determined according to the amount of sensitivity inflicted on the specified environment. In total, in the area under consideration, about 30 percent were defined as very high sensitivity areas.
