森林火灾对生态系统结构与功能的影响及恢复策略
摘 要
森林火灾作为自然界的重大灾害之一，对全球生态系统结构与功能构成了严重威胁。火灾不仅直接破坏植被结构，导致物种多样性的急剧下降，还深刻影响土壤结构与养分循环，干扰水文结构与水资源平衡。本研究针对森林火灾对生态系统结构与功能的影响及恢复策略进行了系统探讨。在结构影响方面，研究分析了火灾对植被结构与物种多样性、土壤结构与养分循环、水文结构与水资源平衡的破坏作用。在功能影响方面，研究揭示了火灾导致的碳汇功能与气候调节能力削弱、生物多样性维持功能退化以及生态服务功能损失与恢复难度增加等问题。针对这些影响，研究提出了自然恢复与人工干预协同作用、基于生态演替规律的恢复路径设计以及社区参与与可持续管理机制构建等恢复策略。

IMPACT OF FOREST FIRES ON ECOSYSTEM STRUCTURE AND FUNCTION AND RECOVERY STRATEGIES
ABSTRACT
As one of the major disasters in nature, forest fires pose a serious threat to the structure and function of the global ecosystem. Fire not only directly destroys the vegetation structure, leading to a sharp decline in species diversity, but also profoundly affects the soil structure and nutrient cycle, and interferes with the balance of hydrological structure and water resources. In this study, the effects of forest fires on ecosystem structure and function and their restoration strategies were systematically explored. In terms of structural influence, the damage effect of fire on vegetation structure and species diversity, soil structure and nutrient cycle, hydrological structure and water resource balance was analyzed. In terms of functional impact, the study reveals the problems of carbon sink function and climate regulation, degradation of biodiversity maintenance function and increased loss and recovery of ecological services. In view of these effects, the study puts forward restoration strategies such as synergistic effect of natural recovery and artificial intervention, restoration path design based on ecological succession law, and construction of community participation and sustainable management mechanism.
