摘要Diel hysteresis occurs often between soil CO2 efflux (R-S) and temperature, yet, little is known if diel hysteresis occurs in the two components of R-S, i.e., autotrophic respiration (R-A) and heterotrophic respiration (R-H), and how diel hysteresis will respond to future rainfall change. We conducted a field experiment in a desert ecosystem in northern China simulating five different scenarios of future rain regimes. Diel variations of soil CO2 efflux and soil temperature were measured on Day 6 and Day 16 following the rain addition treatments each month during the growing season. We found contrasting responses in the diel hysteresis of R-A and R-H to soil temperature, with a clockwise hysteresis loop for R-H but a counter-clockwise hysteresis loop for R-A. Rain addition significantly increased the magnitude of diel hysteresis for both R-H and R-A on Day 6, but had no influence on either on Day 16 when soil moisture was much lower. These findings underline the different roles of biological (i.e. plant and microbial activities) and physical-chemical (e.g. heat transport and inorganic CO2 exchange) processes in regulating the diel hysteresis of R-A and R-H, which should be considered when estimating soil CO2 efflux in desert regions under future rainfall regime.
