【摘要】 在帽儿山人工林中,笔者整理了定点观测资料,对林内可燃物的含水率与气象因子关系进行了多元线性回归分析,并建立了相应的数学模型。为防火期中预测三种不同类型内可燃物的含水率,预报各类型火险等级的数量化指标提供理论依据。更多还原

【Abstract】 A stationary study on the changes of water content of combustible substances (sticks and litter) in oak, scotch pine and larch forest stands was conducted in Maorshan Artificial Forest Experimental Statation. The conclusion is that the changes is the integrated effects of climatic factors. A model of poly-regressionat analysis was also established, will provide a theoratical basis for the predication of water content in combustible substances in the three types of forests and the numerical indexes of fire danger classes of them.更多还原
