森林可燃物含水率与森林火灾危险性的研究

Study on the Relation between the Moisture Content of Forest Inflammable Material and Forest Fire Danger

通过对森林群落小气候和可燃物含水率变化的观测,研究森林群落可燃物含水率的变化规律。分析了柞木林、山杨林、硬阔林、人工落叶松林、踏头草甸五种不同类型森林群落内的气象因子和可燃物含水率变化,与标准气象站数据的差异及相关性。在此基础上,探讨利用标准气象因子与森林可燃物含水率之间的相关关系,预测森林火灾危险性的可能性和方法。

In this paper, regularity on the change of moisture content of forest inflammable materials in relation with forest fire was studied through the measurement of forest moisture content and observation on the forest microclimate. Studies were conducted in 5 types of forest colonies: oak stand, aspen stand, hard broadleaf stand, larch plantation and forest land with mosses. Besides, the data from the local standard weather stations were also used for comparison for variance analysis. Based on the results, possibility and methods for prognosis of forest fire danger by means of meterological data from the local weather stations were discussed.
