| 中文摘要: |
| 激发效应是调控土壤有机质分解的重要指标之一，它是指外源有机物料的添加所引起的土壤有机质分解在短期内剧烈改变的现象，是影响土壤碳库动态的关键过程。本文对土壤有机质激发效应理论国内外相关研究进展进行了凝练分析，分别阐述了“共代谢”“氮矿化”“化学计量比”“底物优先利用”和“土壤微生物碳泵”5种代表性土壤有机质激发效应理论及其特点，分析了影响土壤有机质激发效应的主要因素，即外源添加物的性质特征、添加量、土壤理化性质及环境因素等，并提出未来应加强微生物机理、影响因素和实践应用价值等方面的研究。 |
| 英文摘要: |
| The priming effects is one of the important indicators to regulate the decomposition of soil organic matter, which refers to the phenomenon that the decomposition of soil organic matter is dramatically changed in a short period caused by the addition of exogenous organic materials, and is a key process that affects the dynamics of soil carbon pool. In this paper, the relevant research progress of the priming effect theory of soil organic matter in China and abroad was summarized, and five representative theories and characteristics of the priming effect of soil organic matter such as“co-metabolism”“nitrogen mineralization”“stoichiometric ratio”“substrate priority utilization” and“soil microbial carbon pump”were expounded respectively, and the main factors affecting the priming effect of soil organic matter：the properties and characteristics of exogenous additives, addition amount, soil physicochemical properties and environmental factors, etc. were analyzed. The future research should be strengthened in microbial mechanism, influencing factors and practical utilization value. |
