Abstract：Based on the result of the national survey of peat resources, the data of organic matter content, volume weight, peat reserves and peatland area were used to estimate organic carbon storage and discuss characteristics of China’s peatlands. The total organic carbon storage (OCS) of China’s peatlands, including bare peatlands and buried peatlands, were 1.503 billion tons, unevenly distributed over 31 provinces and 16 climatic zones. Peatland OCS (POCS) in Sichuan (645 million tons) and Yunnan Provinces (291 million tons) was the largest, accounting for 62.29% of the total POCS. Plateau humid zone had the largest POCS of 714 million tons, especially in Zoige Plateau, where POCS was 630 million tons, accounting for 41.92% of the total POCS. The organic carbon density (OCD) of China’s peatlands was generaly between 80kg/m3 and 140kg/m3, and the range of the maximum was 270~360 kg/m3, and the minimum was less than 80kg/m3. Divided by Yan Mountain, Taihang Mountain and Hengduan Mountain, peatland OCD was lower on the northwestern side than that on the southeastern side. The average OCS per unit peatland area averagely was 143.97kg/m2, and that in the south of Yunnan Plateau was 637.06kg/m2. The average regional organic carbon intensity of peatlands averagely was 208.23t/km2,and that in Zoige Plateau (3972.71t/km2) was the largest.
