Bamu National Park, has witnessed an annual fire and its repetition for many years. Considering the importance of preserving the park and its proximity to Shiraz refinery, fire hazard zoning was conducted using geographical information system (GIS) and Analytic hierarchy process (AHP). With regards to the four factors of physiography (elevation, slope, direction), climate (temperature and precipitation), human factors (tourism, industrial areas, military regions, residential areas and roads) and fuels (vegetation type and density) and weighting according to digital layers, expert opinions, questionnaire filling and integration of manufacturing layers, the final mapping of fire zoning classified into 0-20 (no risk), 20-40 (low risk), 40-60 (medium risk), 60-80 (risky) and 80-100 (high risk). The results showed that 23. 3% (14263 hectares) and 20. 25% (2. 84) of the area were located in the dangerous and very dangerous zones, respectively. Evaluating the provided model accuracy showed that 76. 60% of the previously fired areas located in dangerous and very dangerous zones, and this subject shows the adaptation of the reality with the prepared maps. With a logical connection between the risk areas and the real places, the success of this method can be proved. So, it is suggested to develop a particular crisis management plan and increase the equipments and human resources for preventing fire and its spread in dangerous and very dangerous zones.
