| 摘 要： | 农田是温室气体的重要排放源,降低农田温室气体排放对减缓全球气候变化具有重要意义。生物质炭是生物质在缺氧条件下热解产生的固体物质,因其含碳量高、难于分解、比表面积大、疏松多孔等特性,已成为农田温室气体减排研究中人们关注和研究的热点。通过综述农田添加生物质炭对温室气体CO2、CH4和N2O排放的影响及其机制,以及对温室气体净排放[包括净增温潜势(NGWP)、温室气体净排放(NGHGE)和温室气体排放强度(GHGI)]的影响等方面的国内外研究进展,并结合目前国内外生物质炭的研究现状,提出了未来生物质炭在农田温室气体减排领域的研究方向,旨在为生物质炭在农田温室气体减排中的应用提供思路和参考。

| Abstract: | Cropland is one of the important sources of greenhouse gas(GHG) emissions. Reducing GHG emissions from croplands is of great significance for mitigating global changes. Biochar is the carbon(C)-rich solid material obtained from biomass pyrolysis in an oxygen-limited environment. Due to its high C content, highly porous structure, large specific surface area and considerable recalcitrancy, biochar has become a hotspot in the study of mitigating GHG emissions from croplands. This paper reviewed the recent progresses in the impacts and mechanisms of biochar amendments on GHG(CO2, CH4 and N2O) emissions from croplands as well as the effects of biochar on net global warming potential(NGWP), net greenhouse gas emissions(NGHGE) and greenhouse gas intensity(GHGI). We also proposed further studies on the mitigation of biochar on GHG emissions. |
