河北省丰宁县森林可燃物含水率与气象要素的关系模型

可燃物含水率的大小决定森林燃烧的难易程度,而可燃物含水率又与气象要素有着密切关系。本文以丰宁县内油松为研究对象,利用统计回归方法分析可燃物含水率与气象要素的关系模型,结果表明当日的降水量、观测前5 天平均相对湿度及当日的最高温度对可燃物含水率影响最大。

Model of Relationship between Moisture Content of Forest Combustibleand Meteorological Factors in Fengning County of Hebei Province

The size of combustible water content determines the difficulty of forest combustion, and the com?bustible water content is closely related to meteorological factors.In this paper, pinus tabulae in fengningcounty was taken as the research object, and the statistical regression method was used to analyze the rela?tionship model between combustible moisture content and meteorological elements.The results show that theprecipitation of the day, the average relative humidity of the 5 days before the observation and the highesttemperature of the day have the greatest influence on the moisture content of combustible material.
