| 摘 要： | 借鉴加拿大林火天气指数(FWI)系统,改进其计算方法。利用大兴安岭地区1966-2006年的气象数据,得到历史上雷击火发生时的火险天气指数,统计分析确定我国大兴安岭地区森林雷击火发生的火险天气等级。根据实地采样测定的可燃物的含水率对计算方法进行了验证。通过统计雷击火发生的火灾级别来检验划分雷击火发生火险天气等级方法的合理性。

| Abstract: | This paper presents the calculation method of the Canadian Forest Fire Weather Index System.By using the historical fire and weather data of Daxing＇anling from 1966 to 2006,the lightning-caused wildland fire weather indexes are calculated according to the improved method of the Canadian Forest Fire Weather Index System.The lightning-caused wildland fire weather danger rating for Daxing＇anling region is determined by statistical analysis.In order to verify the improved calculation method correct,we measured the moisture content of forest floor little fuel in the Daxing＇anling region.We study the rationality of the lightning-caused wildland fire weather danger rating divided through the lightning-caused wildland fire rating classified by burned area. |
