| 摘 要： | 人类活动显著影响着全球大气循环格局，全球平均温度升高导致干旱事件发生幅度、频度和持续时间增加，这对森林生态系统带来更多的是负面影响.本文基于已有研究，系统总结了干旱事件对森林生态系统地理分布格局、群落结构重建、植物生长和生理特性、死亡和灭绝、植物生产力以及碳循环功能的影响及其机理，并对未来干旱事件对森林生态系统长期效应以及在不同时间尺度上作用机理的研究提出建议.本研究对开展全球变化背景下森林生态系统对干旱事件响应机制的研究具有重要指导意义.

| Abstract: | Due to the intensification of human activities,the pattern of global atmospheric circulation is significantly affected.The increase of global average temperature leads to the increase of the magnitude,frequency and duration of drought events,which has a significant effect on the forest ecosystem.Based on the existing research,this paper systematically summarizes the effects of drought events on the geographical distribution pattern,community structure reconstruction,plant growth and physiological characteristics,death and extinction,plant productivity,and carbon cycle function of forest ecosystems.To this end,future research should focus on the long-term effects of drought events and the mechanisms of action at different time scales on forest ecosystems.It has important guiding significance for the research field of forest ecosystem response mechanism to drought events in the context of global change. |
