摘要：

农田土壤的固碳潜力有助于评估农田土壤作为大气二氧化碳的“源”或“汇”的功能，进而正确评价农田土壤对全球气候变暖的影响。土壤有机碳固定和损失的研究是目前国际上前沿研究领域之一，然而土壤有机碳的动态变化还存在许多不确定性，这就为测定农田土壤碳的固定潜力带来了困难。本文围绕土壤有机固碳的基本问题，总结了农田土壤有机碳固定及其影响因素的国内外研究进展。

Abstract:

Understanding the potential of cropland soils to restore soil organic carbon (SOC) would help to evaluate the contributions of cropland soils as a C source or C sink and assess the influence of cropland soils to global warming correctly. Investigation of SOC storage and loss is one of the global front-ledge research areas. However, there were many uncertainties about SOC dynamics in soil system, which brought difficulties to determine the potential of cropland soils to restore C. Based on discussing the basic theory of SOC sequestration, this paper summarized the research of SOC sequestration and it’s affecting factors.
