Deciphering soil properties, carbon, nitrogen and phosphorus ecological stoichiometric patterns and the potential affecting factors is the basis to reveal response mechanisms of peatlands in Tibet to climate change. Based on information of 10 typical peatlands and soil samples collected on July 23-29, 2015, soil organic carbon, total nitrogen, total phosphorus and potassium contents were analyzed. The results showed that herbaceous plants like Carex parva, Carex aristulifera and Blysmus sinocompressus are the main peat-forming materials, while moss is generally mixed with other plants. Most peatlands are observed in lake basin, flood plain, river channels and fan edge depressions. Mean contents of ash, soil organic matter, humic acid, total nitrogen, total phosphorus and total potassium are 39.06%、58.99%、33.63%、1.55%、0.17% and 0.81%, while mean soil ratio of carbon and nitrogen, ratio of carton and phosphorus and ratio of nitrogen and phosphorus in molecular were 36.2、363 and 9.72, respectively. No significant and pairwise correlations between soil organic carbon, total nitrogen and total phosphorus were found, which indicated that no consistent ratio of carbon, nitrogen and phosphorus existed in peatland soils of the Tibet. Also, no significant correlations were found between annual temperature or precipitation and soil organic carbon, total phosphorus, ratio of carbon and nitrogen, ratio of carton and phosphorus and ratio of nitrogen and phosphorus respectively, indicating that current climate change might have little influence on soil properties of peatlands in the Tibet.
