Based on the feasibility of DNDC(denitrification-decomposition) model in the hilly-gully areas of the Loess Plateau,which was verified by the 8-year soil organic carbon(SOC) data derived from long-term experiment,continuous SOC changes and carbon cycle features on the slope land were studied by using DNDC model.The study not only provides scientific basis for increasing the region s agricultural soil fertility and farm production,but also makes a corresponding contribution to scientific reducing,therefore i...
