摘  要：
研究农田土壤有机碳库动态特征及其过程机制,不仅可降低人类对未来气候预测的不确定性,而且可为农田土壤固碳和生产力保育的技术选择和政策制定提供理论依据。南方农区是我国粮食主产区,该区80%的耕地是水田,因此,研究南方水田土壤有机碳动态具有重要的科学价值和现实意义。通过大量文献的综述分析,对农田土壤有机碳库分组、稳定机制和试验方法的研究现状和发展趋势进行了系统总结,在此基础上,结合实践经验,提出了南方水田土壤有机碳研究的关键问题和重点领域。

摘  要：
Understanding of soil organic carbon dynamics and its mechanisms in farmland will not only reduce the uncertainty of global climatic prediction,but also provide the theoretical references for technology selection and incentive policy making for farmland productivity conservation and carbon sequestration in soil.Southern region is the main area of grain production in China,and paddy field accounts for 80% of the farmland in this region.To study on soil organic carbon dynamics in paddy field of south-China has significant importance in science and national demand.Based on a broad review of a lot of references,a detailed summary was given for the research status and advances in the components and stability mechanism of soil organic carbon pool and the experimental method.According to the author's research experience and field survey results,finally,the key scientific problems and main research fields were put forward for future study on soil organic carbon dynamics in paddy field of south-China.
