This study predicates the prone areas for developing Avicennia Marina forests along the coastal areas of Hormozgan province by studying the oceanography features influencing these forests and using logistic regression models. Tidal areas, flooding level, salinity of water and waves were considered as independent variables. The prediction of prone areas was based on using logistic regression model and the validity of the model was studied by ROC test and Pseudo-R2 . The results of this study indicates that; firstly the maximum wave height, the average maximum flooding level and the level of sanity of water are significantly associated with the presence of Mangrove and the high level of parameters of ROC and Pseudo-R2 confirm the validity of the model. Secondly the maximum wave height was introduced as the main marine parameter influencing the Mangrove communities. Finally the eastern part of the Persian Gulf coast, the west coast of Oman, and a few small spots in the easternmost parts of the coastal zone of Hormozgan province, were found as the most suitable areas for developing Mangrove forest.

We used 6 criteria and 29 indicators for determination environmental sensitivity of geomorphologic aspects of the coastal area in Hormozgan. Identification and determination of the important coefficient showed exclusivity and wilderness are the most important coefficients and industrial dependency had the lowest priority for determination of the environmental sensitivity in this regard.Moreover, in order to, determine importance and priority of sensitivity of ecosystems in the study area 9 physical structure were studied in both shore and coastal zone (include: 4 structure in coastal area and 5 structure in shore area). According to the results, Inundated mudflat and in shore area and Low flat land in coastal area are of the most important sensitivity .After reviewing the physical structure and preparation map of overlaying this structure, sensitivity zoning was developed coastline in Hormozgan province on 5 class of sensitivity, Very low sensitivity, low sensitivity, moderate sensitivity, high sensitivity and very high sensitivity. Zoning of sensitive physical structure in coastal zone shows the lowest extent areas are in Low sensitive degree and the most extent areas are in moderate sensitive degree in physical sensitivity classes.According to the results, shore area in Hormozgan province that includes 11.35% of coastal zone has high physical sensitivity. In shore area Inundated Mudflat, Rocky shore and Inundate beach have most physical sensitivity and inundated process is the most important phenomena on the structures mentioned the shores. The most sensitive of coastal area is Low flat land.
