Due to the emergence of problems such as global warming and the increase in the concentration of greenhouse gases in the atmosphere year by year, the "double carbon" action, especially carbon neutrality, has had a wide-ranging impact around the world. National leaders have mentioned at many important meetings that "dual carbon" should be included in the overall layout of economic and social development and ecological civilization construction. At the same time, it is mentioned that the synergy of pollution reduction and carbon reduction should be taken as the general starting point for promoting the comprehensive green transformation of economic and social development. During the "14th Five-Year Plan" period, my country's ecological civilization construction has entered a critical period of focusing on carbon reduction, promoting the synergy of pollution reduction and carbon reduction, promoting the comprehensive green transformation of economic and social development, and realizing the improvement of ecological environment quality from quantitative change to qualitative change. To achieve the goal of building a beautiful China, the "Double Carbon" action will play a very important role. Accurate simulation of the carbon cycle is the key to realizing the "double carbon" action.
DNDC (Denitrification-Decomposition, denitrification-decomposition model) is currently one of the most successful models for simulating biogeochemical cycles in the world. Dynamic simulation models for virtually all terrestrial ecosystems. In the international high-level symposium on "Applying Long-term Observation Data to Evaluate Soil Organic Matter Models", DNDC was rated as one of the better models for soil carbon pool assessment.
