| 摘 要： | 土壤有机碳和土壤结构是衡量土壤地力的重要指标,同时也是影响土壤稳定性和生产力的主要因素。土壤有机碳对团聚体的形成和稳定具有重要作用,而土壤团聚结构对土壤有机碳的累积与分解具有显著影响。回顾了有机碳影响团聚体形成稳定作用的模式模型;归纳了土壤团聚体对有机碳累积的保护作用机制。在总结土壤有机碳和土壤团聚体相互作用机制的基础上,探讨了农田管理措施对土壤有机碳和团聚体的影响,并概括了目前国际上相关研究的新技术。并在此基础上,提出了在该领域研究中存在的问题,以期为中国土壤地力的持续提升研究提供参考。

Research Process of the Interaction Mechanism Between Soil Organic Carbon and Soil Aggregate |
| |
| Abstract: | Soil organic carbon and soil aggregate are the important indicators of soil fertility, which greatly influence the stability and productivity of soil. Soil organic carbon plays an important role in the formation and stability of soil aggregate, and soil aggregate significantly affects the accumulation and decomposition of soil organic carbon. The modes of the stability formation of soil aggregate affected by soil organic carbon were reviewed. The protective effect of soil aggregates to organic carbon ccumulation was summarized. The effects of farmland management on soil organic carbon and soil aggregate were discussed based on the interaction mechanisms for soil organic carbon and soil aggregate. The new international technologies were summarized. On this basis, the problems existed in this study area were proposed, this paper could provide reference for the improving of soil fertility in China. |
