| 摘 要： | 围绕生物炭稳定性概念,论述了其影响因素,并对比分析生物炭稳定性的研究方法及预测模型。结果表明,生物炭稳定性的基础是其具有高度芳香化结构和土壤团聚体的保护作用,温度、原料及环境条件是影响生物炭稳定性的主要因素,生物炭稳定性最优评估方法为同位素标记法和双指数模型相结合,但其仍具有一定的局限性。在此基础上,指出不同土壤类型、轮作方式及预测模型是当前生物炭稳定性研究的前沿领域和深化方向。

| Abstract: | The influence factors of biochar stability are discussed on the basis of its concept,and the research methods and prediction models of biochar stability are comparatively analyzed.The results show that the stability of biochar is attributed to highly aromatic structure and protective effect of soil aggregates.The main factors affecting biochar stability are temperature,raw materials and environmental conditions.The optimal evaluation method for biochar stability is to combine the isotope labeling with double exponential model.Then,it is pointed out that different types of soil,crop rotations and prediction model is the development direction of current biochar stability research. |
