祁连山东端气象因子与青海云杉林火险等级相关性分析

Analysis of Relationship between Meteorological Factors and Fire Risk Rating of Qinghai Spruce Forest in the Eastern End of Qilian Mountain

通过对祁连山东端青海云杉林可燃物含水率与气象因子相关性分析,采用统计回归法,建立了青海云杉林可燃物含水率与气象要素关系模型,以青海云杉林死体可燃物引燃含水率为基准,结合燃烧实验,确定了祁连山东端青海云杉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,为祁连山东端青海云杉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 Qinghai spruce forest in the eastern end of Qilian Mountain,the relationship between the moisture content of combustibles and meteorological elements in Qinghai spruce forest 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 Qinghai spruce forest in the eastern end of the Qilian Mountain 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 Qinghai spruce forest in the eastern end of the Qilian Mountain.
