Abstract

Temperature response of soil respiration depends on the sensitivity and adaptability of soil respiration (SR) for the variation of soil temperature, which will directly influence the terrestrial carbon cycling and extent prediction of global warming. The diurnal and seasonal variations in the temperature response of SR were assessed through continuous measurement during the June 2012 – May 2013 with an automated chamber system under 3 vegetation types in the hilly region of Mount Taihang, China. Because of the differences of plant physiology and environment conditions, temperature sensitivity of soil respiration (Q10) varied among vegetation types. The seasonal variation of Q10 was primarily driven by soil temperature while soil moisture had little influence on the dynamic for each site based on annual scales. However, due to the complicated relation between soil properties and SR, Q10 value derived from diurnal and seasonal patterns of SR should be used with extreme caution when estimating carbon balance of terrestrial ecosystem
