ABSTRACT
The aim of this study is to analyze the factors that affect the occurrence of fires in the vegetation, in the area of the Serra do Brigadeiro State Park (PESB) and its surroundings, and through this information to establish the most appropriate methodology to generate a risk map for fires in the place. A risk cartogram for fires was developed with the help of the ArcGIS 10.1 software, by the generation of maps of slope, aspects and land use. These maps were intercrossed, enabling the determination of the areas most susceptible to fires. Tested methodologies varied in the form of assigning grades to each predictor class of fire as well as in the division of risk classes. According to the results, the assignment of notes to each predictor class, depending on the size of the burned area and taking into account the history of events, reflected the risk of fires in vegetation in the region more satisfactorily.
