Abstract:

Forest fires have the characteristics of wide distribution,high frequency and strong uncertainty.The assessment of forest fire risk can provide references for effective prevention and control of forest fires and reduction of losses.The evaluation index system of forest fire risk is constructed from three dimensions of meteorology,terrain and combustibles.It is the first time to introduce hesitant fuzzy linguistic description,which improves the flexibility of expert language evaluation expression.Through the hesitant fuzzy linguistic hybrid weighed aggregation operator,to aggregate the linguistic information,then get the probability of fire risk in a certain area.This method has been applied to an over fire area of Daxinganling forest to assess the risk of forest fire in this area,and this case proves the feasibility and effectiveness of this method.

Key words: forest fire risk, hesitant fuzzy linguistic, hesitant fuzzy linguistic hybrid weighted aggregation operators
