摘要: 稻田是大气CH4和N2O的重要排放源,减少稻田CH4和N2O排放对缓解全球气候变暖具有重要意义。生物炭具有含碳量高、难分解、比表面积大、疏松多孔等特性。利用生物炭可改善稻田土壤理化性质及微生物学性质,减少温室气体的排放,提高水稻产量。在现有相关研究的基础上,结合国内外研究进展,回顾了国内外生物炭的研究历史及特性,全面评述了生物炭影响稻田温室气体排放的作用机理,以及对稻田温室气体CH4和N2O排放、综合温室效应(GWP)、温室气体排放强度(GHGI)、净生态系统经济预算(NEEB)的影响等国内外研究进展,提出了未来生物炭在稻田温室气体排放方面的研究方向。

Abstract: 【Objectives】Paddy field is one of the important sources of greenhouse gas (GHG) emissions. Reducing GHG emissions from paddy field is of great significance for mitigating global climate changes. Biochar has the characteristics of high carbon content, difficult decomposition, large specific surface area, highly porous structure and considerable recalcitrancy. Biochar could effectively improve soil properties and microbial properties, reduce the emission of CH4 and N2O, and increase rice yield. 【Method】Based on current research, the characteristics of biochar, the mechanism of biochar affecting GHG emissions from paddy field, effects of CH4 and N2O emissions, global warming potential (GWP), greenhouse gas emissions intensity (GHGI), the net ecosystem economic budget (NEEB) at home and abroad were comprehensively reviewed by combining with the latest research progress. 【Result】The future prospects about the mitigation of biochar on GHG emissions from paddy field were also discussed.
