摘要： The DeNitrification-DeComposition (DNDC) model isa process model with a series of carbon and nitrogen biogeochemistry in agro-ecosystems. It incorporates the driving factors of the ecological environment and aims to simulate the carbon and nitrogen cycle in the terrestrial ecosystem. Furthermore, the model can be applied effectively in a paddy ecosystem. Based on an investigation and literature review, this study summarized and analyzed the impact of agricultural practices such as water management, fertilizer application, and straw incorporation on greenhouse gas emissions and soil carbon storage. After years of improvement, the DNDC model can presently be used effectively to evaluate the carbon sequestration and emissions mitigation potential of various agricultural practices. However, the related details of scientific processes of agricultural management, such as biochar incorporation and plastic mulching in paddy fields, should be added or modified and combined with experimental cases of actual agricultural practices to complete the calibration of the model, provide theoretical support for its promotion, and establish a reliable method of evaluating carbon sequestration and emissions mitigation in paddy fields. & COPY; 2020 The Authors.
