Simulation of carbon dioxide fluxes in agroecosystems based on BIOME-BGC model

Carbon cycle of terrestrial ecosystem is one of the hot issues in global change science. And there are more difficult during study with agroecosystem because of the strong affect caused by human activities such as sowing, fertilizing and irrigation. In this study, a measurement is carried out in Guantao, Hebei Province, China, which is a typical argoecosystem station. In this paper, carbon dioxide fluxes in Guantao, were simulated by BIOME-BGC model as well, and the result was compared with the eddy covariance (EC) data. The result shows that the trend curves of simulated data and observation data were well matched in growing season of winter wheat in 2009.
