摘要
对吉林省1969—2013年间发生的森林火灾情况进行分析,结果显示,受森林防火条例有效实施的影响,1984年后林火发生次数显著降低并趋于稳定;春、秋两季为林火高发季节,且在进行森林防火资源的调配过程中,火灾次数较多的4月和5月应以控制火源为主要目的,受害森林面积较大的9月应以强化扑火能力为工作重点;此外,月初林火发生概率相对较高,应针对该时间段提高防火警惕;林火的发生主要集中在8:00—16:00,需重点部署防火工作,而且2:00左右受害森林面积相对较大,火灾扑救能力应需加强。
The forest fires in Jilin Province between 1969 and 2013 were analyzed in this study. Because the forest fire prevention ordinance was effectively carried out,forest fire frequency significantly reduced and then seemed to be stable after 1984.Spring and autumn were the high-occurrence seasons for the forest fires,and the government should put the ignition source control as the focus of fire prevention work in April and May,and fire resistance capacity should be strengthened in September. The probability of fires is relatively high at the start of months,and the time period should attract enough attention.The forest fires in study area were mainly concentrated in 8: 00-16: 00,the fire protection work should be deployed primarily during the period. The fire fighting ability should be improved around 2: 00 for high forest area burnt.
