%X The time-dependent atmospheric CO 2 concentrations since 1860 are rebuilt with a one dimensional model of global carbon cycle. The results show that: (1) an excellent agreement exists between the observations in Mauna Loa and the model simulations; (2) the cean is the most important sink of anthropogenic CO 2 , but its ability ad a carbon sink is limited by the buffer effect. The uptake rate of CO 2 by the ocean also relates closely to certain courses of the response; (3) the cosystem acts as a dual role in the global carbon cycle. It is a source because of human being impacts and, at the same time, a sink due to its response to the excess atmospheric CO 2 . Since the industrial era, destruction of the ecosystem byhuman activities and recovery by itself has been of same order of magnitude; and (4) the terrestrial biosphere shortens the response time of the whole carbon cycle system to the anthropogenic perturbations.
