摘要
森林火险区划是林火管理的基础。利用层次分析法将影响森林火险的静态因子评判指标分成三个层次,根据专业知识确定各因子权重,充分利用现有的可燃物和地形数据信息,以徂徕山林场为例进行了森林火险区划。区划结果表明,徂徕山林场大部分地区的火险为中低火险,高和极高火险区域面积分别占林场总面积的11.6%和3.1%。本研究为林场尺度上开展科学的火险区划提供技术参考。
Forest fire risk zoning is based on classification of forest fuel in combination with fire environment,which is the basis for forest fire management.In this paper,the analytic hierarchy process is used for forest fire risk zoning.The static factors affecting the forest fire risk are divided into three levels and their weights are determined by professional knowledge.In this method the available data of fuel and topography can be fully used.A case study for CuLai Mountain Forest Center is used for this technique.The results show that most parts of the study area is in low fire risk rating,and the high and very high fire risk zones account for 11.6%and 3.1%.This study can be used as a technical reference for forest fire risk zoning on the forest center scale.
