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.
