Estimate of soil organic carbon density and its stock in Fujian Province

The total organic carbon stock in soils of Fujian Province was estimated by using the analytical data of the second soil investigation in Fujian Province. The result showed that the total organic carbon stock in soils of Fujian Province was 1575661?106 t and the average value of carbon densities was 145.23 t·hm-2 and higher than that of average level in China. Red soil, yellow soil and rice soil were the main types in Fujian Province and the organic carbon stocks of them were also three main parts of soil carbon slock in Fujian Province, occupying 9381% of Fujian pools. The carbon densities of red soil, yellow soil and rice soil were 146.107 t·hm-2, 257675 t·hm-2 and 111.633 t·hm-2, respectively, and they all were higher than the average carbon density of China.
