	<span style=\"font-size:14px;\">文章综述了土壤有机碳的赋存状态及其变化对地球碳汇的影响，重点分析了影响土壤有机碳的气候、土层深度、母质、地形、粘粒含量、时间、植被等因子的作用；提出了增强土壤有机碳库存的措施，主要有保护性耕作、提高土壤微生物的活性、施肥管理、退化土壤修复、灌溉等，预测了未来土壤有机碳研究的主要方向。<br />
This paper summarized the occurrence of soil organic carbon and its change on the impact of the earth’s carbon sink, focused on the impact of climate, soil depth, parent material, topography, clay content, time, vegetation and other factors on soil organic carbon storage, and put forward measures to enhance soil organic carbon inventory, including conservation tillage, improving soil microbial activity, fertilization management, remediation of degraded soil, irrigation, etc. The main research directions of soil organic carbon in the future are predicted. </span>
