AB  - Elucidating the response mechanism of soil respiration (Rs) to silvicultural 
      practices is pivotal to evaluating the effects of management practices on soil 
      carbon cycling in planted forest ecosystems. However, as common management 
      practices, how thinning, understory plant removal, and their interactions affect 
      Rs and its autotrophic and heterotrophic components (Ra and Rh) remains unclear. 
      Therefore, we investigated Rs, Ra and Rh by the trenching method from 2011 to 
      2015 in a Pinus tabuliformis plantation in northern China, subjecting to four 
      treatments (intact control plots [CK], thinning [T], understory removal [UR], and 
      thinning with understory removal [TUR]). Mean annual Rs was significantly 
      increased by thinning (by 15.3%), whereas decreased by UR (by 17.4%), compared 
      with CK. These variations in Rs were mainly attributed to changes in Ra. The 
      increments of Ra were caused by the enhanced growth of fine root biomass after 
      thinning. However, UR led to lower Ra compared with CK (p < .05), indicating that 
      understory growth is inadequate to compensate for the decreased respiring root 
      biomass induced by understory removal. Rs was unchanged between TUR and the 
      intact control plot due to the opposite effects of thinning and UR on the Ra. 
      Changes in Rh exhibited no significant differences among the treatments, partly 
      because of the stable microbial biomass carbon (MBC) and forest floor mass 
      (litter and fine woody debris). No interaction effect between thinning and 
      understory removal was detected on Rs, Ra, and Rh. The lowest temperature 
      sensitivity (Q(10) ) value of Ra was found in CK. This study highlights the 
      necessity of incorporating understory plant effects on soil CO(2) efflux in 
      assessing forest management practices on soil carbon cycling.
