摘要
针对吉林省森林火灾发生发展特点,引入加拿大林火天气指标系统,利用1996—2008年吉林省森林火灾数据和气象资料,研究系统中火险等级的划分,为其进行本地化运行提供具体参数修正。结果表明,加拿大林火天气指标系统输出的指标值(CFFM、IIS、IFW等)与吉林省实际发生林火次数具有良好的相关性,系统输出的火险等级与实际情况较为匹配,其分级方法经验证能较好地描述吉林省的火险等级,系统能较好地适用于当地。但由于一些客观因素,还需要从其他方面进一步试验或研究,以使系统能够更好地适用于吉林省的森林防火工作。
Aiming at the occurrence regularities of forest fires in Jilin Province,a new fire danger classification method was developed by means of the statistical data on forest fires and meteorological data collected from 1996 to 2008 in Jilin Province according to the Canadian forest fire weather index system. The parameter emendation and test results indicate that the output index values from Forest Fire Weather Index( FWI) system are well correlated with the actual fire occurrence. It is also verified that the classification of fire danger ratings can better describe the fire danger rating in Jilin Province,and the FWI system is suitable for the local fire weather danger classification.
