英文摘要	To address the issue of lacking data in the non-growing season,we conducted an experiment in a coastal wetland of the Yellow River Delta from October 29,2016 to February 9, 2017,by continuously monitoring soil CO_2 concentration and temperature at different soil depths (15,30,and 45 cm). In order to understand the dynamics of CO_2 efflux and to assess its relationship with soil CO_2 concentration,we measured CO_2 efflux in March 3-5 and March 16-18, 2017. The results showed that soil CO_2 concentration significantly increased with the increases of soil depth. At the same depth,soil CO_2 concentration was significantly higher in autumn than in winter. There was strong diurnal variation in CO_2 efflux,which was consistent with the variation of surface soil temperature. The temperature sensitivity coefficients (Q10) of soil respiration were 3.49-3.74. There was a significant positive correlation between CO_2 efflux and soil CO_2 concentration or soil temperature. Using the derived relationships,we estimated CO_2 efflux for the nongrowing season,and found that the three models produced similar magnitudes and variations, i.e.,0.44 to 0.57,-0.18 to 0.01 and 0.09 to 0.13 μmol·m~(-2)·s~(-1) for the maximum,the minimum and the mean values,respectively. Our results demonstrated the effects of soil carbon trans- formation in non-growing season on carbon cycling of the Yellow River Delta wetland.
