摘要
在全球变暖背景下森林火灾发生的危险性持续增加,可燃物是唯一可人为调控的火环境因子。与天然林相比,人工林结构简单,且以富含油脂的纯林为主,同时多为中幼龄林,易发生森林火灾。文中从人工林可燃物特点及其与林火引燃和火行为的角度出发,综述了人工林可燃物管理技术,对管理中存在的问题进行了分析,建议今后人工林可燃物管理在降低森林易燃性和燃烧性的同时,还须充分考虑管理技术对生态系统和林木生长的影响,优先选择对生态环境友好且促进林木生长的技术和措施。
The risk of forest fires occurrence continues to increase in the context of global warming. Forest fuel is the only fire environment factor that can be controlled. Compared with natural forests, plantation forests have a simple structure, most of which are oil-rich pure forests. Additionally, these forests are mostly middle-aged and young forests, which are prone to forest fires. From the perspective of fuel characteristics and their relationship with fire ignition and fire behaviors, this paper reviews the plantation fuel management technologies, and analyzes the problems existing in the management. It is suggested that the future fuel management technologies should fully consider their effects on ecosystem and the growth of trees while reducing the flammability and combustibility of forests, and the technologies which are friendly to environment and capable to promote the tree growth should be preferred.
