摘要:

森林可燃物作为森林燃烧三要素之一,其载量、燃烧特性和连续性分布均会影响林火的发生、蔓延和防控。森林可燃物作为林火发生的物质基础和必要条件,是林火蔓延的主要载体。一旦发生高强度火灾会严重破坏森林生态环境和森林资源。开展森林可燃物调控,减少可燃物积累,改善可燃物的燃烧特性以及改变其水平和垂直连续性,对降低林火风险,减小林火强度有重要意义。本文从可燃物调控技术(人工调控、机械清除、计划烧除、化学除草、微生物降解、营造生物防火林带等)和评价方法(林火行为、森林燃烧性、火灾风险和生态效应等)2方面,综述了国内外研究现状,总结归纳了森林可燃物调控技术和调控效果评价方法,对比了不同调控措施的有效性,分析了各种评价方法的优缺点。并对可燃物调控技术的未来研究方向和评价方法进行了展望,提出需要开展森林可燃物的基础研究,针对性探讨适宜重点火险区的调控措施,并长期监测和动态评估调控效果,量化调控效果的时间变化及生态环境影响。在理解阻火原理的基础上,提出以“绿色防火”理念结合森林生态调控等综合技术,助力实现“双碳”目标,是未来森林防火研究与管理的重要方向。

Abstract:

Forest fuels are the material basis for forest fires and the main carrier for the spread of forest fires. As one of the three elements of forest combustion, the load, combustion characteristics and continuous distribution of forest fuels affect the occurrence, spread and prevention of forest fires. Once a major fire occurs, it will cause serious damage to the forest ecosystem and forest resources. Therefore, it is of great significance to carry out forest fuel management, reduce fuel accumulation, improve the combustion characteristics, change their horizontal and vertical continuity to reduce forest fire risk and intensity. This article summarizes the current research status at home and abroad from two aspects: combustible control technology (manual control, mechanical removal, planned burning, chemical weed control, microbial degradation, and the construction of biological fire prevention forest belts) and evaluation methods (forest fire behavior, forest combustibility, fire risk, and ecological effects, etc.). Summarized and collated forest fuel control technology and evaluation methods for control effectiveness, the effectiveness of different regulation measures is compared, and the advantages and disadvantages of various evaluation methods are analyzed. The future research directions and evaluation methods of fuel control technology are prospected. It was pointed out that basic research on forest fuel should be carried out, appropriate control measures should be discussed for key fire risk areas, long-term monitoring and dynamic evaluation of control effect should be carried out, and the time change of control effect and ecological environment impact should be quantified. On the basis of understanding the principle of fire resistance, it is an important direction for future forest fire prevention research and management to help achieve the goal of “carbon peaking and carbon neutrality” by combining the concept of “green fire prevention” with comprehensive technologies such as forest ecological regulation.

Key words: fuel management, prescribed burning, mechanical removal, biological firebreak, forest fire behavior, flammability
