| 中文摘要: |
| 作为世界上最大的发展中国家之一，中国粮食生产对于全球粮食安全以及气候变化都具有至关重要的影响。近二十年来，大量研究表明粮食作物田间生产过程是温室气体甲烷（CH4）和氧化亚氮（N2O）的重要排放源。伴随着生命周期评价法（碳足迹）在农业领域的运用，越来越多的研究表明，除了田间生产过程以外，农业生产资料生产过程排放的温室气体同样不可忽视。本文综述了我国在粮食作物生命周期生产过程中温室气体排放的研究，提出了针对性的温室气体减排措施，并对我国未来农作物生产过程的碳足迹研究进行了展望。 |
| 英文摘要: |
| As one of the largest developing country in the world, food production in China has substantial influence on global food security and climate change. During the past two decades, mountainous studies have proved that the sector of field cultivation of food crops is an important source of greenhouse gas(GHG)emissions. However, as the application of life-cycle analysis(carbon footprint)in the research field of agriculture, more and more studies have pointed out that the sector of agricultural materials production is also an important source of GHG emissions, which should not be ignored. This paper reviewed the research studies conducted during the past two decades regarding the assessment of GHG emissions due to the life-cycle production of food crops in China, proposed mitigation options and put forward prospects and suggestions on carbon footprint-related research studies in future. |
