Forest gaps are common disturbances in forest ecosystems and play a crucial role in forest regeneration.By adjusting illumination,temperature,humidity,soil physicochemical properties,and other environmental factors,forest gaps reshape local micro-environments,thereby regulating the structure,diversity,ecological functions,and successional dynamics of soil microbial communities.This review summarizes the effects of forest gap induced micro-environmental changes on soil microbial communities,with an emphasis on how gap characteristics,including size,age,formation mode and position,regulate microbial community structure and function.On this basis,it concludes the key roles of plant-soil-microbe interactions within canopy gaps in nutrient cycling,energy flow and ecosystem stability maintenance.It also identifies limitations in current research,including insufficient understanding of microbial functional group responses to forest gaps,inconsistent classification criteria for forest gap characteristics,and limited long-term monitoring of natural forest gaps.Future studies should strengthen long-term field observations and controlled experimental studies to deepen the understanding of the ecological effects of forest gaps,thereby providing a scientific basis for sustainable forest ecosystem management and biodiversity conservation.
