摘要
土壤碳库是陆地生态系统中最重要以及最大的碳库,在全球碳循环中的作用非常重要。添加外源有机碳可以影响土壤原有有机碳矿化,从而导致正激发效应或者负激发效应的产生,进而影响土壤的碳库。本文对激发效应的影响因素以及激发效应产生的机理进行了总结说明,并且为今后的研究内容以及方向提出了建议。
Soil carbon pool is the most important and largest carbon pool in terrestrial ecosystems, and it plays a very important role in the global carbon cycle. The addition of exogenous organic carbon can affect the mineralization of the original organic carbon in the soil, leading to positive or negative priming effect, which in turn affect the soil carbon pool. This article summarizes the influencing factors of the priming effect and the mechanism of the priming effect, and provides suggestions for the content and direction of future research.
