Abstract :
In this research, various environmental and social criteria were used to determine areas prone to fire in Shurdara region of Golestan province, and then a map related to each factor was prepared to determine high risk areas of fire. Shannon's entropy method was used to weight the criteria in this research. Then, according to the weight and value of each criterion for each sub-area, the data related to the sub-areas were analyzed using the Electr III technique. In this way, the implementation of the Electr method included: making a decision matrix, weighting the criteria, making a normal matrix, distillation process (determining favorable and unfavorable criteria), calculating the indicators of harmony and inconsistency, and finally ranking the options completely. According to the results of the research, sub-areas 3 and 8 are areas with high potential for fire. Also, the results of the current research showed that sub-areas 1 and 2 were classified and identified as sub-areas with low potential for fire. To evaluate the final map, the map of fire-prone areas resulting from the method used in this research was compared with the map of fire areas prepared by the General Department of Natural Resources of Golestan province. The result showed that based on the kappa coefficient obtained which is equal to 0.82, the map has good and acceptable accuracy. Therefore, the proposed method is proposed as a reliable screening method to identify areas at risk of fire, which can help the authorities to guide preventive measures.
