摘要
稻田生态系统是重要的碳库,它具有碳源和碳汇双重功能.充分发挥稻田碳汇功能对推进低碳绿色农业生产方式和保障农业可持续发展具有重要意义.稻田水肥管理模式很大程度上影响了温室气体的排放和稻田碳固存能力.本文综述了近年来DNDC模型在稻田水肥管理中的应用研究进展.从稻田生态系统固碳减排角度出发,总结了稻田水肥管理措施对温室气体CH4和N2O排放、土壤碳库和作物生产固碳的影响,评价了不同稻田轮作模式的固碳减排效应,并展望了 DNDC模型在未来稻田生态系统的应用前景.研究结果将为未来稻作生产固碳减排,实现农业生产可持续发展提供理论参考.
Abstract
Paddy field is an important carbon pool,with dual functions of carbon source and sink.Maximizing its sequestration potential is essential for promoting low-carbon and green agriculture production modes and ensuring sustainable agricultural development.The management modes of water and fertilizer in paddy fields greatly impact greenhouse gas emission and carbon sequestration capacity.We conducted a comprehensive review on the applica-tion of the DNDC model in water and fertilizer management of paddy field.We summarized the effects of various wa-ter and fertilizer management measures on greenhouse gas emission(CH4 and N2 O),soil carbon pool,and crop carbon sequestration in paddy fields from a perspective of carbon sequestration and emission reduction.Further-more,we evaluated carbon sequestration and emission reduction effects of different paddy rotation modes.Lastly,we described the application prospects of the DNDC model in paddy fields.The findings presented herein will serve as a valuable theoretical reference for promoting carbon sequestration and reducing carbon emission in rice produc-tion,and facilitating sustainable development of agricultural production.
