Based on data from ChinaFLUX this study analyzed the daily value flow processes of carbon fixation, monthly value distribution, and daily accumulative processes in a year of two kinds of typical forest, two kinds of grasses and a farmland. The results showed that the annual value of carbon fixation of these ecosystems was different, and flow processes and cumulative processes followed different trends over a year. The sequence of the five kinds of ecosystems based on the annual value of carbon fixation from largest to smallest was Yucheng warm temperate agriculture ecosystem (Yucheng), Qianyanzhou subtropical artificial coniferous forest ecosystem (Qianyanzhou), Changbai Mountain temperate mixed coniferous broad-leaved forest ecosystem (Changbaishan), Haibei alpine meadow ecosystem (Haibei)and Dangxiong alpine meadow ecosystem (Dangxiong). Variability in the daily and monthly carbon fixation at Qianyanzhou was the smallest, followed by Changbaishan, Yucheng, Dangxiong and Haibei. The cumulative processes of daily carbon fixation for the five kinds of ecosystems were well fitted to cubic curves.
