摘要
可燃物类型及其载量分布是决定林火行为的重要因素。以北京西山试验林场魏家村分场为研究区域,根据样地调查和森林清查数据对可燃物类型进行分类,并对可燃物载量的空间分布进行研究。根据历史气象数据确定当地平均最大风速平均值为3.6m/s,平均最大风速的最大值为14m/s,在此情景下,结合DEM数据和可燃物数据对研究区域的林火强度进行计算,并对防火林带的有效参数进行确定。
Distribution and loading of forest fuel is the determinant factor that influences forest fire behavior. In this paper, we studied the fuel and potential fire intensity under the scenario of average maximal wind speed and maximal value of average maximal wind speed derived from the records from 2000 to 2006 in Weijiacun Forest Center. We classified the forest fuel and stud- ied the fuel spatial distribution based on forest inventory and sample plots. Vertical and horizontal distribution of fuel is calculated from sample plots and tree biomass equation. Based on fuel distribution, wind simulation and DEM, fire intensity and effective shaded fuelbreak width are calculated under the condition of crown fire occurrence.
