摘要
随着极端天气的常态化,森林火灾发生频率不断上升,大火后造成的火烧迹地已成为生态修复亟需关注的目标。结合文献分析、实地调研与总结归纳等方法,对极端天气背景下火烧迹地的发生与修复的必要性进行讨论,明确了“火灾作为生态系统破坏因子”的讨论语境。从森林生态系统、地形地势、火烧影响与灾害评估视角对林火迹地进行认知,反映出林火迹地生态修复的复杂性,提示需要结合地情、灾情妥善制定修复策略。最后,以迹地异质性与可持续发展性视角为牵引,结合2022年夏季重庆北碚缙云山山火后的迹地修复实例,引介“灾害评估,明确目标”“迹地平整,创造条件”“重构林相,优化林分”“健全机制,后期保障”的生态修复流程。以期为极端气候下林火迹地的修复与管理策略提供参考。
With the normalization of extreme weather,the frequency of forest fires is increasing,and the burned land caused by fires has become the object of urgent attention for ecological restoration.Combining the methods of literature analysis,field investigation,and summary,the necessity of the occurrence and restoration of burned land under the background of extreme weather was discussed first,and the discussion context of“fire as an ecosystem damage factor”was clarified.Then,from the perspective of forest ecosystem,topography,fire impact,and disaster assessment,the cognition of forest fire land reflects the complexity of forest fire land ecological restoration,suggesting that it is necessary to properly formulate restoration strategies based on the land and disaster conditions.Finally,guided by the perspective of heterogeneity and sustainable development of the miraculous land,combined with the example of the miraculous land restoration after the Jinyun Mountain fire in the Beibei District of Chongqing in the summer of 2022,the ecological restoration process of“disaster assessment,clear goals,”“miraculous land formation,creating conditions”,“reconstruction of forest phase,optimization of forest stand,”“sound mechanism,the latter part of security”is introduced.The study is expected to provide a reference for the restoration and management strategy of forest fire land under extreme climates.
