生物炭作为缓解气候变化策略的理想热解产物,投入土壤后可以存留成百上千年,其正效应表现在提高作物产量、增强土壤肥力和土壤持水性能等方面.本文从近期国内外生物炭研究文献出发,研究筛选关于生物炭制备方法及其特殊稳定性的文献资料,最终从各异的环境条件、生产原料角度推出估算生物炭(生物炭碳素)稳定性3种方法,即间接测量法、直接测量法和分子特性法.指出生物炭源因热解速率、热解温度和缺氧程度的广泛性,生产出来各种生物炭类型的稳定性需要建立新机制评估,以便多角度去评价生物炭生产和改良土壤的前景和限制性.

As a promising pyrolysis product for mitigating climate changes, biochar can be remained in soil for thousands years after field ap-plication. The positive benefits of biochar amendment into soil include crop yield increase, soil fertility improvement and water-holding ca-pacity enhancement. The objective of this study is to quantify specific stability of the biochar by screening the relative documents towards di-rections including feedstock classification, biochar preparation, unique stability, etc. Finally three types of methods were summarized, such as indirect measurement methods, direct measurement methods and molecule properties methods for biochar stability, which resulted from vari-ous production conditions and feedstocks. Wide range of biochar feedstocks and specific stability of biochar preparation required new evalu-ation mechanism in order to evaluate prospect of biochar production process and relative soil amelioration and limitation with multiple per-spectives.
