利用生物质废弃物制备生物炭,被认为是一种非常有前景的并能够实现碳封存和减缓气候变暖目的的管理策略。生物炭施入土壤后对温室气体N2O排放的影响,增加或抵消部分生物炭固碳的效果。简要介绍了生物炭的定义及特性并重点概述了生物炭施入土壤后对温室气体N2O排放影响的国内外研究现状、影响因素及机理,并对生物炭影响土壤N2O排放的未来研究方向进行了展望。
The use of biomass wastes for biochar production is considered to be a very promising management strategy for carbon sequestration and mitigation of climate change. The impact of biochar application on soil N2O emissions from greenhouse gases to increase or offset the effect of some biochar carbon sequestration. This paper briefly introduced the definition and characteristics of biochar and summarized the research status, influencing factors and mechanism at home and abroad about the impact of biochar on soil N2O emissions after biochar application. The future research directions of biochar affecting soil N2O emission were also discussed Outlook.
