摘要
以北京松山林场10种优势树种活枝和活叶为研究对象,通过锥形量热仪模拟真实火场环境,测定多项燃烧相关参数,并运用统计分析工具进行因子分析、相关性分析及主成分分析。研究结果表明:10种树种热释放能量峰值在162~233 kW/m^(2),点燃时间在4~13 s;总烟释放速率峰值为30~672 m^(2)/s。燃烧性从大到小为杏树(Armeniaca vulgaris)>油松(Pinus tabuliformis)>蒙古栎(Quercus mongolica)>柳树(Salix babylonica)>榆树(Ulmus pumila)>白蜡(Fraxinus chinensis)>杨树(Populus davidiana)>国槐(Sophora japonica)>丁香(Syringa villosa)>侧柏(Platycladus orientalis)。本研究为北京地区防火灭火提供了理论依据和数据支撑。
In this study,living branches and leaves of ten dominant tree species collected from Beijing Songshan Forest Farm were taken as the research objects,a real-fire environment was simulated by cone calorimetry,a series of combustion-related parameters were measured,and factor,correlation and principal component analysis were performed with statistical software.The results showed that the peak heat release rate of the 10 species ranged from 162~233 kW/m^(2),with ignition times spanning 4~13 seconds.The peak total smoke release rate varied from 30~672 m^(2)/s.PCA indicated the flammability order from highest to lowest asArmeni a ca vu lgaris>Pinus t abu liformis>Qu ercus mongo lica>Sa lix baby loni c a>Ulmus pumil a>Fraxinus chin e nsis>Populus davidi an a>Soph or a japonica>Syringa vill os a>Pl atyc l adus orientalis.This research provides theoretical and data support for fire prevention and suppression in Beijing.
