| Abstract: | On the basis of a brief introduction of the DNDC model (denitrification decomposition model) and its application and improvement in China, this paper reviews the research progress of Chinese scholars in simulating and estimating greenhouse gas emissions and emission reduction and regulation in farmland by using this model, and proposes that the future model development in China should be based on the characteristics of China''s agricultural planting system, add the model module, modify the model parameters, establish a cross-scale farmland ecosystem comprehensive assessment model, and strengthen the large-scale and long-term time series of greenhouse gas emissions simulation and prediction research. At the same time, the combination of remote sensing and GIS technology and models should be strengthened to improve the accuracy of regional scale simulation and prediction and reduce the uncertainty of simulation results. |
