摘要
云南松是一种广泛分布于我国西南地区的易燃树种,其特殊的地理位置、气候气象、森林类型、林内生产生活用火的复杂和多样,导致云南松林的森林火灾次数较多,经济损失较大。通过对云南松林燃烧有关性的文献期刊、统计数据进行归纳整理和数据分析,结果表明,现有云南松林燃烧性的研究方法主要以热重分析法(TG)、锥形量热仪分析(CONE)、室内模拟点烧法和野外点火计划烧除为主,其它方法为辅。综合不同实验统筹分析其燃烧性,云南松是一种点燃性水平较低,剧烈性高,持续性中等,损耗性高的易燃树种。未来云南松林燃烧性研究将向燃烧多维模拟和多指标定量评估的方向发展,探讨云南松在垂直方向的燃烧连续性、发生树冠火的水平连续性、量化可燃物载量、火灾蔓延速度、灾后森林生态恢复等。
Pinus yunnanensis as a kind of inflammable tree species widely distributed in southwest China leads to forest fires and economic losses for the special geographical location and the complex and diverse climate,forest types and production and living fire.By summarizing and analyzing the literature,periodicals and statistical data related to the combustibility of Pinus yunnanensis forest,the results showed that the existing research methods were mainly thermogravimetric analysis(TG),cone calorimeter analysis(CONE),indoor simulated ignition and field ignition plan combustion,supplemented by other methods,and the different experiments were combined to analyze the combustibility.Pinus yunnanensis is a kind of inflammable tree species with low ignitability,high intensity,medium persistence and high loss.In the future,the research of Pinus yunnanensis forest combustibility will be developed in the direction of multi-dimensional simulation and multi index quantitative evaluation,such as discussing the combustion continuity of Pinus yunnanensis in vertical direction,horizontal continuity of crown fire,quantifying fuel load,fire spreading speed,forest ecological restoration after disaster,etc.
