林火动态研究与林火管理

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。

Research Achievements of Fire Regime and Fire Management

Fire regime is a stable indicator of ecosystem sustainability.The understanding of forest fire dynamics and fuel characteristics is the basis for making fire management strategy or plan.Fire regime is closely related to fuel accumulation process.The paper reviewed the research achievements on fire regime and fuel accumulations.Fire regime is affected by factors such as topography,vegetation,climate,etc.Since climate,vegetation and human activities have changed in many regions,the fire regime has undergone s...
