| 摘 要： | 作为世界上最大的水稻生产国以及氮肥消耗国,我国农业生产过程排放了大量温室气体甲烷(CH4)和氧化亚氮(N2O)。因此,减少农田土壤CH4和N2O排放以及提高土壤碳库储量(简称“固碳减排”)对于缓解全球气候变暖以及确保粮食安全至关重要。近20年来,我国在农田土壤固碳减排方面进行了大量研究,总结出了一系列行之有效的固碳减排措施。本文综述了我国目前针对农田土壤温室气体减排以及土壤有机碳固定的有效措施,并对未来农田土壤固碳减排方向进行了展望。

| Abstract: | As the largest crop-production and fertilizer-consumption country in the world, food production in China has emitted substantial greenhouse gases(methane, CH4; nitrous oxide, N2O) into the environment. Therefore, it is essential to mitigate the CH4 and N2O emissions and increase soil organic carbon sequestration (also known as "mitigation and sequestration")in croplands for retarding global warming and ensuring food security. During the past two decades, mountainous studies have conducted on this research area and have summarized a series of agricultural management practices, which are effective in mitigating CH4 and N2O emissions and increasing soil organic carbon sequestration in the cropland of China. This paper reviewed these effective "mitigation and sequestration" agricultural management practices and put forward prospects and suggestions on future studies regarding this research area in China. |
