摘要:

森林火灾具有分布广、频率高、不确定性强的特点,对森林火灾发生风险进行评估可以为有效防治森林火灾发生、降低损失提供参考。从气象、地形、可燃物3个维度构建森林火灾发生风险的评价指标体系,首次引入犹豫模糊语言描述,提高专家语言评价表达的灵活性。通过犹豫模糊语言混合加权集结算子对语言信息进行集结,得到某区域火灾发生风险的可能性。该方法被应用到大兴安岭森林某片过火地区,对该地区森林火灾发生风险进行评估,证明了该方法的可行性和有效性。

关键词: 森林火灾风险, 犹豫模糊语言, 犹豫模糊语言混合加权算子

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
