摘　　要：利用锥形量热仪测定了木荷Schima superba叶片在不同辐射强度和不同叶处理方式的火发生指数,并探讨了木荷燃烧性能测试方法。锥形量热仪辐射强度分为40,45,50,60,70 kW.m-2等5种处理,叶片处理方式包括边长为0.5,1.0,1.5,2.0 cm的正方形和全叶等5种处理。外部点燃条件下测试木荷的燃烧性能。采用DPS数据处理系统,对不同辐射强度和不同叶处理方式的火发生指数分别进行差异性显著检验。分析结果表明,辐射强度为40 kW.m-2,边长为0.5 cm的正方形叶片和全叶的火发生指数均值较高,与其他处理的差异性较显著,能够较好地反映出处理之间的差异,测试树种的燃烧性较为合理。To determine combustibility of Schima superba, the Fire Proceeding Index of S. superba fresh leaves （ squares with 0. 5, 1.0, 1.5, and 2.0 cm sides as well as the whole leaf） under different intensities of radiation （40, 45, 50, 60, and 70 kW·m^-2） and processing modes was tested using a cone calorimeter and outer ignition probe into the testing methods. Data Processing System was used to test discrepancies in the fire proceeding index. Results showed discrepancies with two different treatments that were obtained from S. superba leaves. Comparing the different radiation intensities and the different leaf sizes, we found that the Fire Proceeding Index was significantly greater with a radiation intensity of 40 kW·m^-2 and leaf sizes of both 0. 5 cm and the whole leaf.
