农业管理措施对土壤有机碳固存潜力影响的研究进展

回顾了近年来国内外农业管理措施对土壤有机碳(SOC)固存潜力影响的研究进展,分析了土壤碳库的源汇效应及其影响因素,着重介绍了耕作制度、轮作制度、施肥制度和残茬管理等农业管理措施对土壤有机碳固存潜力的影响,指出应加强对土壤有机碳固存潜力和农业管理措施对土壤有机碳库影响的研究,以便制订合理的农业管理政策,进而缓解全球变化。参31。

Research advances in the effect of agricultural management on soil organic carbon sequestration

Research advances in the effect of agricultural management on the soil organic carbon(SOC) sequestration in recent years were reviewed in this paper;the effect of sink or source of soil carbon pool and its influencing factors were discussed.In the meanwhile,agricultural management influencing carbon sequestration,such as tillage,rotation,water and nutrient management,and residual management were introduced in depth.Eventually,the focuses that the study about the influences of carbon sequestration and agricultural management on soil organic carbon pool should be strengthened were put forward in order to establish reasonable policy of agricultural management,consequently to alleviate global changes.
