从潜在林火行为的角度出发,依据可燃物的关键参数,利用系统聚类方法在丰林自然保护区建立标准森林可燃物模型.结果表明:丰林自然保护区可建立3个标准可燃物模型,代表性植被类型分别为阔叶红松林(模型FL-Ⅰ)、云冷杉林(模型FL-Ⅱ)和杨桦林(模型FL-Ⅲ).依据可燃物的林分结构与组成、地表覆盖类型、水平与垂直连续性等,本研究建立的FL-Ⅰ、FL-Ⅱ和FL-Ⅲ模型与加拿大CFBPS可燃物分类系统中的C-5、C-2和D-1模型相似.3个标准可燃物模型的地表和垂直结构特征,可为野外工作者判定可燃物模型提供帮助.
Based on the key parameters of combustibles, the standard forest combustibles model was established in Fenglin Nature Reserve by means of systematic clustering from the perspective of potential forest fire behavior.The results showed that three standard combustibles models could be established in Fenglin Nature Reserve , And the representative vegetation types are broad-leaved Korean pine forest (model FL-Ⅰ), spruce-fir forest (model FL-Ⅱ) and poplar (model FL-Ⅲ) .According to the structure and composition of the combustible forest stand, The FL-Ⅰ, FL-Ⅱ and FL-Ⅲ models established in this study are similar to the C-5, C-2 and D-1 models in the Canadian CFBPS combustibles classification system. Three standard combustibles The surface and vertical structural features of the object model can help field operators to determine the combustibles model.
