【摘要】 根据福建省第2次土壤普查的基本数据对福建省土壤有机碳储量和密度进行估算,结果表明:福建省土壤 有机碳总储量为1 575.661×106t,平均有机碳密度为145.23 t·hm-2,高于全国平均水平。红壤、黄壤和水稻土作 为福建省面积分布最广的土壤类型,其有机碳储量占福建省土壤有机碳总储量的93.81％;其有机碳密度分别为 146.107 t·hm,2、257.675 t·hm-2和111.633 t·hm-2,均高于全国平均水平。更多还原

【Abstract】 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 1575. 661×106 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 93. 81% of Fujian pools. The carbon densities of red soil, yellow soil and rice soil were 146. 107 t·hm-2, 257. 675 t·hm-2 and 111. 633 t·hm-2, respectively, and they all were higher than the average carbon density of China.更多还原
