摘要
森林地表可燃物燃烧性能分析是研究森林火险的基本内容之一。对沈阳地区分布的六种主要林型地表可燃物的燃烧性指标进行实验测定,分别得到不同林型下地表可燃物的燃点、燃烧热值、灰分率和粗脂肪率。采用加权赋分法计算其综合燃烧性能,结果表明,油松、落叶松和樟子松林型下地表可燃物燃烧性最强,刺槐和天然杂木林型下地表可燃物燃烧性较强,而杨树人工纯林下地表可燃物的综合燃烧性最弱。研究结果可为沈阳地区森林火险的安全控制提供理论参考。
Analysis the combustion performance of the forest surface fuel is one of the basic contents for forest fire insurance. The combustion indexes are measured of six main types of forest surface combustible materials in Shenyang area,and burning point,combustion calorific value,ash rate and crude fat rate under different forest types were obtained respectively.The comprehensive combustion performance is calculated by the weighted assignment method. The results showed that the surface fuel combustibility is strongest under pinus tabulaeformis,larch and Mongolica forest; acacia and natural miscellaneous wood forest is stronger,and artificial pure forests is the weakest. The research results provide theoretical reference for the safety control of forest fire risk in Shenyang area.
