Auto- (RA) and heterotrophic respiration (RH) exhibited significantly diurnal and seasonal variations.
- class="label">•
The contribution of RA to RT exhibited remarkable diurnal and seasonal variations.
- class="label">•
The seasonal variation of RA/RT presented a bimodal curve for AS and VN sites.

RA is more sensitive to the variation of soil temperature than RH.

Dormant season may have greater soil respiration potential than growing season in our study area.
