Abstract:

On the basis of taking into account the main feedback relations of carbon cycle terestrial surface system,the authors employ highly integrated and simplified methods to establish a carbon cycle zero-dimension model of land surface system (CCZDM),and study carbon fluxes among four carbon reservoirs (land biota, litter carbon, soil carbon and atmospheric carbon), by taking impact of human activities and ocean influence as external factors. The CCZDM supposes that Human Being's impacts are not enough to break the natural balance of carbon cycle before the year 1860, but since then the balance has been broken owing to the industrial revolution. A large quantity of CO 2 was emitting into the atmosphere by burning fossil fuels, intensifying agriculture and destroying segments of the vegetation cover of the earth. With the increase of atmospheric CO 2 , the global temperature increased accordingly, which, in turn , affects carbon cycle of terrestrial system. The changes of four carbon reservoirs and temperature are simulated through CCZDM from the year of 1860 to 1997 and the results show that the simulated data are compatible with observational as well as other research findings. This demonstrates that the model is reasonable and the parameter values are correct. The study of CCZDM can provide theoretical guides to that of two-dimension carbon cycle of land surface system.

Key words: carbon cycle, zero-dimension model, temperature, terrestrial surface system, feedback mechanism
