Climate models forecast more frequent and a longer period of drought events which may impact forest soil carbon dynamics, thereby altering the soil respiration (SR) rate. We examine the simulated drought effects on soil CO2 effluxes from soil surface partitioning heterotrophic and autotrophic soil respiration sources. Three replicates of drought plots (6 x 6 m) were constructed with the same size of three control plots. We examined the relation between CO2 and soil temperature and soil moisture, each being measured at a soil depth of 15 cm. We also compared which factor affected CO2 efflux more under drought conditions. Total SR, autotrophic respiration (AR) and heterotrophic respiration (HR) were positively correlated with soil temperature (p < 0.05), and the relationships were stronger in roof plots than in control plots. Total SR, AR, and HR were negatively correlated only in roof plots, and the only HR showed a significant correlation (p < 0.05, r = -0.59). Soil respiration rates were more influenced by soil temperature than by soil moisture, and this relationship was more evident under drought conditions.
