祁连山保护区东端气象因子与阔叶林火险等级相关性分析
|
摘要
通过对祁连山保护区东端阔叶林可燃物含水率与气象因子关系分析,采用统计回归法,建立了阔叶林可燃物含水率与气象要素关系模型,以阔叶林死体可燃物引燃含水率为基准,结合燃烧实验,确定了祁连山保护区东端阔叶林森林火险等级对应的气象因子,结果表明:森林可燃物含水率模型模拟效果较好,引入森林可燃物含水率气象预测模型可提高森林火险气象指数模型的应用效果,为祁连山保护区东端阔叶林火灾预测预防提供了科学依据。
Based on the analysis of the relationship between the moisture content of combustibles and meteorological factors in the Broad-leaved forests in the eastern end of Qilian Mountain Reserve,the relationship between the moisture content of combustibles and meteorological elements in Broad-leaved forests was established by statistical regression method.Based on the pilot water content rate,combined with the combustion experiment,the meteorological factors corresponding to the forest fire risk grade of the Broad-leaved forests in the eastern end of the Qilian Mountain Reserve were determined.The results show that the forest combustible water content model has a good simulation effect and introduces the forest combustible moisture content.The meteorological prediction model can improve the application effect of the forest fire risk meteorological index model,and provide a scientific basis for the prediction and prevention of fire in the Broadleaved forests in the eastern end of the Qilian Mountain Reserve.
