Abstract. Forest and grassland fires are one of the major natural hazards in the East of Mongolia.The aim of the present study is to set up, assess and validate Hybrid Fire Index as a new fire risk index over study area. This site frequently faces grassland and forest fire. The following variables were derived for the study area: vegetation moisture, slope, aspect, elevation, distance from roads, and location of population. Those variables were weighted based on their impact on the fire risk. According to probability distribution analysis of Hybrid Fire Index, Very low (0-20), low (21-40), moderate (41-60), high (61-80)and very high (81-100) risk were defined. Then the generated map of Hybrid Fire Index was classified into five classes. Based on the validation result, the Hybrid Fire Index presented a valuable fire risk map.
