Abstract：In the context of global climate warming,the intensity and duration of high-temperature weather have significantly increased,posing greater stress on the growth of urban trees.The study of heat tolerance in heat-sensitive tree species is a critical issue to address in response to climate change.This paper,based on a review of the current research on heat tolerance in heat-sensitive tree species,analyzes the survival pressures these species face under climate change.It investigates the effects of high-temperature conditions on plant morphology,leaf structure,physiological functions,and growth processes.The paper outlines various methods for assessing plant heat tolerance,including natural high-temperature screening in the field,artificial high-temperature stress simulation,and laboratory physiological and biochemical indicator testing.Based on these findings,an evaluation index system for the heat tolerance of heat-sensitive tree species is proposed,and the limitations in existing research and future directions are discussed.
