摘　　要：森林燃烧性是森林火险评估的基础,也是制定营林防火措施的依据。以北京市八达岭林场18种主要森林类型的地表死可燃物为研究对象,分别以死可燃物负荷量、含水率及综合属性为分析依据,结合国内外最新研究成果、林场实际情况和样地调查,分别讨论并对比不同森林类型的燃烧性,并划分等级。研究得出,以地表死可燃物综合属性为分析依据,研究不同森林类型的燃烧性更符合林场实际情况,并以综合属性为依据绘制林场燃烧性等级图,同时,死可燃物负荷量和含水率的分析,可以为营林防火措施的制定提供理论依据。Forest combustibility is the foundation for fire danger rating system,as well as the theoretical basis for fuel reduction treatments.The combustibility of 18 forest types in Beijing Badaling Forest Farm were studied in this research based on the surface dead fuel.The fuel load,fuel moisture,and integrated attributes were analyzed.Combined with the latest scientific research achievement in this area,the actual situation of forest farm,as well as the sample plots survey,the combustibility of different forest types were discussed and classified.The result shows that the combustibility evaluation which based on integrated attributes is more reasonable,and the forest fire danger map is finished based on the integrated attributes.Also,the surface dead fuel load and fuel moisture analysis can be used as the theoretical basis for the fuel management.
