摘要
通过样地调查和样品处理,分析了八达岭林场3种林型林下各类可燃物的含水率及可燃物负荷量,得出结论:各林型中地被物层含水率最低,负荷量最大,是林下可燃物的主要组成部分;林下可燃物负荷量依次为:油松纯林>油松阔叶混交林>阔叶林,林下可燃物含水率为:阔叶林>油松阔叶混交林>油松纯林;油松林负荷量大,含水率小,又含有较多的油脂,具有较高的火险等级。对油松林提出了相应防火建议。
The moisture content and charge capacity of combustible materials under 3 different forest types were analyzed by plots survey and sample process in Badaling Center. The dead ground covers which were major part of combustible materials contained the highest charge. And the order of charge capacity was as followed： the coniferous results showed that the lowest moisture and the forest 〉 the coniferous and broad 〉 the broad ; the order of moisture content as ： the broad forest 〉 the coniferous and the broad 〉 the coniferous forest. The highest charge and the lowest moisture content as well as much more pine resin made the Pinus tabulaeformis forest have the high risk of forest fire. Then the paper put forward the suggestions for fire prevention.
