Abstract: By evaluating the vulnerability of regional forest fires, it is possible to control fire risks and reduce losses. Taking into account of factors such as the degree of forest fire exposure and the ability to respond to disasters, a regional forest fire vulnerability assessment index system was constructed, which includes 4 criterion levels of exposure degree, recovery index, sensitivity index and disaster response ability and 16 index levels. The combined weighted TOPSIS method was used to carry out forest fire vulnerability assessment in 21 cities (states) in Sichuan Province. According to the assessment results, the vulnerability level of forest fire in Sichuan Province is divided into 5 levels.

Key words: forest fire vulnerability, entropy weight method, coefficient of variation method, technique for order preference by similarity to ideal solution, indicator system
