森林可燃物是森林火灾的物质基础。火灾是森林的最大灾害,给森林造成的损失和其严重后果是,程度取决于林火行为。而在森林火灾的发生、发展及衰退直至熄灭的整个过程中所表现出来的一系列林火行为,除了受自然因子、人为因子的影响之外,它与森林可燃物类型有着极其密切的关系。所谓森林可燃物类型是指可燃物的种类、形状、大小及其配置等都相似的森林可燃物的集合体。由于森林可燃物类型不同,影响到林火发生的难易程度、林火的蔓延速度、林火的种类、林火的强度等都不相同。甚至影响到林火的损失及后果,直至影响到林地恢复所应采取的措施。
Forest fuel is the material basis of forest fires. Fire is the biggest disaster in a forest, and losses to the forest and its serious consequences depend on the behavior of the fire. However, the series of forest fire behaviors that appear during the whole process of forest fire occurrence, development and decline till extinguished are closely related to the type of forest fuel besides the influence of natural factors and human factors. The so-called forest fuel type refers to the type of combustible material, shape, size and configuration are similar to the collection of forest combustible materials. Due to the different types of forest combustibles, which affect the ease of occurrence of forest fires, the spread of forest fires, the types of forest fires, and the intensity of forest fires are all different. It even affects the losses and consequences of forest fires until the measures that should be taken to affect the restoration of forest land.
