It is estimated that the Earth's surface 1m soil organic carbon reserve 1500~2000Pg (1Pg=1015g), Atmospheric CO2 content of the two times, 0.1% of the soil carbon changes will result in atmospheric CO2 concentration circle occurred millionth changes.
据估计,地球表面1m土层中有机碳储量1500~2000Pg(1Pg= 101 5g),为大气CO2含量的2倍左右,土壤碳库0.1%的变化将导致大气圈CO2的浓度发生百万分之一的变化。
