摘要: 从全球和生态系统角度,综述了植物过程对土壤有机碳含量的影响和可能的作用机理,揭示了植物过程对土壤有机碳的源和汇的影响及对土壤有机碳的动态影响,讨论了植物过程对土壤有机碳影响研究的任务和发展前景,及减少土壤表层向空气呼出CO2的数量、维持现时的生态平衡的途径,指出了植物过程影响土壤有机碳的研究方向和有待解决的问题.增加植物生物量,可以增加土壤有机碳贮量.

关键词: 土壤有机碳, 植物过程, 生态系统

Abstract: From the viewpoint of the globe and ecosystem,this paper reviewed the effects and the possible action mechanisms of plant process on soil organic carbon concentration.Plant process could affect the source and sink of soil organic carbon,which was likely related with ambient temperature,and forest process could be in favor of the accumulation of soil carbon.Future tasks in this field were put forward to reduce the CO2 concentration in atmosphere through controlling the respiration of soil surface layer and keeping ecosystem balance.It is crucial to make efforts in increasing plant biomass to enhance soil organic carbon storage.

Key words: Soil organic carbon, Plant process, Ecosystem
