Abstract: From the viewpoint of forest fire behavior, and based on the key parameters of fuels, three standard forest fuel models for the forests differed significantly in fuel characteristics and local environmental conditions in Fenglin Natural Reserve were established by using hierarchical cluster analysis. The three models were FL-Ⅰ, FL-Ⅱ, and FL-Ⅲ for the broadleaved-Korean pine forest, spruce-fir forest, and poplar-birch forest, the representative forest types in the Reserve, respectively. According to the forest structure and composition, land cover type, and horizontal and vertical continuity, the three models FL-Ⅰ, FL-Ⅱ, and FL-Ⅲ were similar to the models C-5, C-2, and D-1 in Canada CFBPS fuel classification system, respectively. The forest ground features and the horizontal and vertical characteristics of the three models established in this paper could help the investigators to identify the fuel types in fuel inventory.

Key words: forest fuel, fuel model, forest fire behavior, Fengling Natural Reserve.
