Abstract 210Pb and 137Cs dating techniques are used to characterize recent peat accumulation rates of alpine peatlands located in Zoige, Tibetan plateau. Several cores were collected in different parts of the peatlands. Cores were 210Pb- and 137Cs-dated, and these data were used to calculate sediment accumulation rates. Ranges of dry mass accumulation rates were 0.021∼0.048 g cm -2 yr −1 (the mean value is 0.033 g cm -2 yr −1). The mean sediment fluxes of SOC, LC and TN in the marsh soil were 113 g m -2 yr −1, 12 g m -2 yr −1 and 5 g m -2 yr −1 seperatly during 1952∼2004 using 137Cs and 210Pb techenique. The changes of SOC, TN and LC accumulation flux were similar with that of the temperature of May.
