摘要: 土壤有机碳库动态变化直接影响全球的碳平衡, 土壤有机碳库研究是全球碳循环研究中的关键。研究人类活动影响下的土壤有机碳库的动态特征及其过程机制,不仅可降低对未来气候预测的不确定性,也可为土壤固碳技术的选择和政策制定提供理论依据。从土地利用方式变化、耕作方式与管理两方面详尽阐述了国内外关于人类活动影响下土壤有机碳库动态的研究进展,提出应加强土地管理、采取适当的农业耕作措施来减少土壤有机碳的流失,以提高土壤对碳的固定。

关键词: 土壤有机碳库, 人类活动, 土地利用, 耕作方式

Abstract: Soil organic carbon pool has a direct effect on global carbon balance, so research of soil organic carbon pool is the key of researches on the global carbon cycling. Understanding of soil organic carbon dynamics and its mechanisms under impact of human activities will not only reduce the uncertainty of predicting climate change in the future, but also provide theoretical references for technology selection and incentive policy making for soil carbon sequestration. This paper reviewed the domestic and overseas study advances on effects of human activities on soil organic carbon pool, especially the effects of land use changes, tillage methods and management practices on soil organic carbon pool. Lastly, some suggestions were presented to mitigate anthropogenic emissions of greenhouse gases, promote carbon sequestration, and maintain sustainable development of agriculture.

Key words: soil organic carbon pool, human activities, land use, tillage methods
