本文在森林燃烧环研究的基础上,将林火行为的两大主要特征(着火蔓延和燃烧强度)分为不同的等级,即着火蔓延序列分为A:难燃、蔓延缓慢;B:可燃、蔓延中等;C:易燃、蔓延快三级,把燃烧强度序列分为Ⅰ:轻度燃烧;Ⅱ:中度燃烧;Ⅲ高度燃烧;Ⅳ:强度燃烧四级,然后以着火蔓延序列为纵向,以燃烧强度序列为横向,构成森林燃烧环网,以此来研究各燃烧环之间的相互关系,分布规律及变型,影响森林燃烧的主要因子是可燃物类型、地形、立地条件、可燃物数量和火灾种类,研究它们在环网上的分布和作用,可为林火管理和估测各燃烧环的火行为特征提供依据。
Based on the research of forest burning ring, this paper classifies the two main characteristics of fire behavior (fire spread and burning intensity) into different grades, that is, the fire spread sequence is divided into A: flame retardant, slow spread; B: flammable, C: flammable, spread quickly three, the combustion intensity sequence is divided into Ⅰ: mild combustion; Ⅱ: moderate combustion; Ⅲ high degree of combustion; Ⅳ: intensity burning four, and then to fire spread sequence for the vertical, In order to study the relationship, distribution and variation of combustion rings, the main factors influencing the forest combustion are combustibles type, topography, site condition, quantity of combustibles And the types of fires, and studying their distribution and function on the ring network can provide the basis for forest fire management and estimation of the fire behavior characteristics of each combustion ring.
