摘要
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。
Turning biomass waste into biochar has been proposed as a promising management strategy for carbon sequestration and global warming mitigation. The effect of biochar addition on soil N2O emission may increase and offset carbon sequestration efficiency in part. In this paper, concept and characteristics of biochar were introduced simply and the research status, influencing factor and mechanism of bioehar addition to soil on N2O emission were described mainly. Moreover, research prospects were briefly discussed on the effect of biochar addition to soil on N2O emission.
