英文摘要	This article suggests that temperature dependence of soil respiration in arid region is reconciled by highlighting a gap in our knowledge by examining the hypothesis that diel temperature sensitivities (i.e. Q(10)) of soil respiration flux ((Rs)) are in essence the same, ignoring the negative (Rs) data in arid regions that characterize more than 30% of the earth's land area. Analyses on data collected from previous studies revealed diel turbulence in Q(10) values even if excluding negative (Rs) data. Such turbulence was inherently controlled by temperature and soil water content. On the basis of utilizing the soil data collected from the Xinjiang and Central Asia Scientific Data Sharing Platform, four coupling models indicated that soil water content and temperature were equally significant in determining Q(10). Therefore, taking into account negative (Rs) data in arid regions is strongly needed to reduce uncertainties in the current global/regional carbon balance and in predictions of future feedback in the coupled carbon-climate system.
