草地土壤团聚体与有机碳固存关系研究进展

Research Progress on the Relationship Between Grassland Soil Aggregates and Organic Carbon Sequestration

土壤团聚体作为土壤结构重要的组成部分,易受到气候变化及人为活动影响。团聚体固碳是认可度较高的固碳措施之一,其固碳功能与土壤团聚体的形成息息相关。本文通过对相关文献的总结,整理了土壤团聚体稳定性及其与有机碳的关系,以草地土壤团聚体为例从放牧及草地退化两个方面分析了草地土壤团聚体的稳定性变化,重点将草地土壤团聚体稳定性变化对有机碳的影响进行系统归纳和总结,提出当前研究的进展、不足并对研究前景进行了展望。

As an important component of soil structure,soil aggregates are susceptible to climate change and human activities.Carbon sequestration by aggregates is one of the highly recognized carbon sequestration measures,and its carbon sequestration function is closely related to the formation of soil aggregates.Based on the summary of relevant literature,this paper sorted out the stability of soil aggregates and its relationship with organic carbon.Taking soil aggregates in grassland as an example,the changes in the stability of soil aggregates in grassland were analyzed from two aspects of grazing and grassland degradation,and the impact of soil aggregate stability changes on organic carbon in grassland was systematically induced and summarized.The progress and deficiency of the current research are put forward and the prospect of the research is prospected.
