摘　　要：对长白山林区主要可燃物类型地表可燃物载量进行了对比分析和聚类分析。通过可燃物类型载量的对比分析,得出易燃的可燃物类型是云冷杉林(鱼鳞云杉103a)、落叶松林(115a)和云冷杉林(鱼鳞云杉80a),最不易燃的是岳桦林(142a)、白桦林(87a)和岳桦林(115a);释放能量最大的可燃物类型是落叶松林(115a),释放能量最小的可燃物类型是白桦林(87a)。通过各可燃物类型的1h时滞可燃物载量和地表总可燃物载量的聚类分析,可把13个可燃物类型化为6类。An experiment was conducted to comparatively analyse the surface fuel loads of principal fuel types in Changbai Mountain forest region. Result showed that flammable fuel types are spruce-fir forest with 80 or 103-year-old Piceajezoertszs and 115-year-old Larix olgensis forest, and uninflammable fuel types are 115 or 142-year-old Betula ermanii forest and 87- year-old B. platyphylla forest. The fuel type with the largest potential energy is Lar/x olgensis forest （115-year-old）, and that with the least potential energy is B. platyphylla forest （87-year-old）. 13 fuel types are classified into 6 groups according to the 1-hour timelag fuel load and the total surface fuel load of each fuel type in cluster analysis.
