Accurate estimation of wetland carbon pools is a prerequisite for wetland resource conservation and implementation of carbon sink enhancement *** inventory approach is a realistic method for estimating the organic carbon pool in China's wetlands at the national *** updated data and inventory approach were used to estimate the amount of organic carbon stored in China's *** results are as follows:(1) the organic carbon pool of China's wetlands is between 5.39 and 7.25 Pg,accounting for 1.3%-3.5% of the global level;(2) the estimated values and percentages of the organic carbon contained in the soil,water and vegetation pools in China's wetlands are 5.04-6.19 Pg and 85.4%-93.5%,0.22-0.56 Pg and 4.1%-7.7%,0.13-0.50 Pg and 2.4%-6.9%,*** soil organic carbon pool of China's wetlands is greater than our previous estimate of 3.67 Pg,but is lower than other previous estimates of 12.20 and 8-10 *** on the discussion and uncertainty analysis,some research areas worthy of future attention are presented.
