To better understand the potential of carbon fixation in China Sea, it is necessary to conduct the researches on the mechanism of carbon fixed and stored by benthic seaweeds, the important primary productivities in marine ecosystems. In this paper, some dominant seaweeds from intertidal zones in Dalian were measured on the daily fixed and respired carbon, and daily release of organic carbon. Furthermore, seasonal variation of carbon fixed and stored by intertidal seaweeds from three seaweed beds in Dalian were elucidated, combined with the measurements of the biomass. The results showed that green algae had the strongest capacity in carbon fixation, followed by brown algae and red algae. The carbon fixed and stored, and organic carbon released by intertidal seaweeds in Dalian were higher in December-May, and lower in June-November. The annual total carbon fixed, and organic carbon released by intertidal seaweeds of each seaweed bed were 1.72×105 g/a and 2.1×104 g/a respectively. The amount of monthly fixed carbon was 1.7 times that of stored carbon.
