Natural radionuclide 210Pb,soil water content,and dry bulk density data were used to calculate the geochronology and characterize the recent peat sedimentation rate of a soil profile obtained near Huahu lake on Zoige plateau.We analyzed the change characteristics of total organic carbon (TOC) content with depth and age,and calculated the recent rate of carbon accumulation (RERCA) of this peat section.It was concluded that the average peat sedimentation rate was 0.16 cm·a~(-1) between 1824 and 2011,which is close to the reported values in other studies on Zoige peatlands.The weighted average sedimentation flux during this time span was 0.082 g·cm~(-2)· a~(-1) and the RERCA was 86.12 g·m~(-2)·a~(-1),which are comparable with the reported values in other researches.The differences indicate the specificity of the peatland formation and development. Using the climate data collected by the weather station,the data of mean annual temperature (MAAT) reconstructed by climate proxies in other researches,and the satellite observated climate data,we found that the main impact factor on climate change on Huahu peatland in recent decades was precipitation,which means that high annual precipitation in that region may contribute to the high carbon accumulation rate.Anthropogenic activities and other factors also constitute an interference in peat and carbon accumulation rate,which needs further study.
