林火动态是一个生态系统可持续性的稳定指标,准确掌握林火动态和可燃物特性是制定合理林火管理策略或规划的基础。林火动态与可燃物积累过程密切相关,了解森林可燃物积累过程是开展林火管理的基础。文中综述了林火动态及可燃物变化的研究进展。林火动态受地形、植被和气候等因素的影响,随着气候、植被和人为活动的变化,许多区域林火动态发生了显著变化,并影响可燃物积累过程及其空间分布。森林结构和可燃物组成的变化会导致火频度、火灾类型和火强度发生变化,林火管理对策也需要相应调整。我国重点林区的林火管理策略也应根据林火动态变化和可燃物情况进行调整,以适应变化的气候和植被条件。
Forest fire dynamics is a stable indicator of ecosystem sustainability. Accurate understanding of forest fire dynamics and combustibles characteristics is the basis for formulating a sound forest fire management strategy or plan. Forest fire dynamics is closely related to the process of accumulation of combustibles. Understanding the process of forest combustibles accumulation is the basis for forest fire management. The paper summarizes the research progress of forest fire dynamics and combustibles changes. The dynamics of forest fire are affected by such factors as topography, vegetation and climate. With the change of climate, vegetation and human activities, forest fire dynamics in many areas have undergone significant changes and have an impact on the process of combustibles accumulation and its spatial distribution. Changes in forest structure and composition of combustibles can lead to changes in the frequency of fires, types of fires and fire intensity, and adjustments in forest fire management measures are also required. China’s key forest fire management strategies should also be based on dynamic changes in forest fires and combustibles to adapt to changing climate and vegetation conditions.
