摘要: 本文论述了三种主要温室气体排放的研究进展以及农田温室气体排放的影响因素。结果表明农田温室气体排放受肥料、耕作方式、土壤水分、温度、质地、有机质、地膜覆盖、机械化操作等多种因素影响。针对农田温室气体减排应主要从减少排放、加强移除、替代(避免)排放等3方面着手,因地制宜,发展新型肥料、合理灌溉、科学地耕作和管理土壤,实现增产增汇减排的可持续发展农业。

Abstract: The research advance on three major greenhouse gases’emission and the influencing factors on farmland greenhouse gas emission are discussed in this paper. The results indicated that greenhouse gas emission from farmland was affected by fertilizers, tillage methods, soil moisture, soil temperature, soil texture, soil organic matter, plastic film mulching, mechanized operation and so on. The reduction of farmland greenhouse gas emission could be carried out from reducing emission, enhancing removal, and replacing (avoiding) emission. To achieve the sustainable development of agriculture with production and income increase and emission reduction should be based on local conditions, new fertilizers’development, rational irrigation, and scientific cultivation and management of soil.
