| Abstract: | Taking the fire statistics of 31 provinces, autonomous regions and municipalities in 2019 as an example, six statistical indicators were selected, including the number of fires, the number of deaths, the number of injured, direct economic losses, burned area and the number of affected households. Factor analysis was used to analyze the indicators, and two public factors that can reflect the fire situation were obtained. Based on the results of factor analysis, the probability of fire occurrence and the consequences of fire are discussed, and suggestions for fire supervision and management are put forward. |
