Popis:	The daytime variation in CO 2 flux between the intertidal sediment and the atmosphere was great and impacted by environmental elements. This paper analyzed the daytime variation in CO 2 flux between the intertidal sediment and the atmosphere and concluded its different rules during the ebb tide and flood tide. During the ebb tide, the CO 2 flux rose as the tide ebbed and its rate of change was different when the redox potential changed (0.13umol m -2 s -1 per 100 cm height of the tide at Eh =500mv). During the flood tide, the CO 2 flux maintained the largest of the day and almost unchanged with the increase of water level. The average CO 2 flux in the flood tide increased with the increase of the redox potential at Eh =500mv. According to these rules, the daytime CO 2 flux can be calculated based on limited measurements well and truly. The fitting straight line equation between the estimated and measured CO 2 flux was y= 0.9353x+0.0872(R 2 = 0.75, P
