The intensity of soil respiration increases with temperature on a global scale. Temperature sensitivity of soil respiration, usually termed as Q10, is defined as the increase in CO2 efflux for a 10°C increase in temperature. In many traditional ecosystem models, Q10 was regarded as a constant. But more and more studies have shown that the observed Q10 values varied greatly in time and space, and that it is of great value to quantify the temporal-spatial pattern of Q10, which involves in the accurate prediction of ecosystem carbon emissions.
