The studies on the response of soil respiration to understory removal are mostly conducted in subtropical forests,but few in temperate forests.There is a close interrelationship between soil respiration,fine root growth,and soil microbes dynamic,while how they respond to the understory removal are still remained unclear,which further limits our understanding in the linteraction between the understory removal and soil respiration,as well as carbon cycling in temperate forests.Therefore,the understory removal...
