摘要
根据火烧试验,研究出来一套包括火险等级、火行为与火烈度等的完整系统.用公式R_0=aT+bV+ch-D计算日燃烧指标R_0(米/分)。此方法曾于1991年5月试用在小兴安岭伊春林区得出满意的结果。
Dependent on the burning experiment,a scheme is presented for dealing with the full range of firedanger grade,fire behavior,and fire severity etc.By means of the formula as following the initialspread rate R_0(m/min) of the wildfire can be calculated.R_0=aT + bV + ch - D where T:day max.air temp.C,V:mean of wind scale at noon,h.lowest RH%,and a、b、c、D are constants.Thescheme had been used on Yichuen fire danger prediction of Siao Xingan mountains May 1991,and ispleased with this Job.
