摘 要
农田土壤有机碳组分及含量影响着土壤与大气间的碳平衡,是衡量全球碳平衡、温室效应及气候变化的重要指标。同时,农田土壤有机碳对土壤的肥力、结构、土壤的理化性质及可持续发展和利用具有重要作用。因此,厘清农田土壤碳含量的影响因素及影响机制对农田固碳增汇及应对气候变化具有重要意义。基于此，作者综述了各因素对农田土壤有机碳的影响机制。

Abstract
The organic carbon composition and content of farmland soil affect the carbon balance between soil and atmosphere, which is an important index to measure the global carbon balance, greenhouse effect and climate change. At the same time, soil organic carbon plays an important role in soil fertility, structure, physical and chemical properties, sustainable development and utilization.Therefore, it is of great significance to clarify the influencing factors and mechanisms of soil carbon content in farmland for carbon sequestration and to cope with climate change. Based on this, this paper reviews the influence mechanism of various factors on farmland soil organic carbon based on the literature data published over the past years.
