摘要
若尔盖高原草地位于中国母亲河上游的水源涵养区域内,对维持高原生态系统的格局具有举足轻重的作用,但该区域生态安全正遭受草地退化、沙化等严重威胁。文章针对若尔盖高原草地典型区,选择土壤团聚体变化典型指标,量化了若尔盖高原草地退化演变进程中土壤团聚体和有机碳变化规律趋势,分析了高原草地退化演变与土壤团聚体和有机碳变化的相关关系。
Zoige Plateau grassland is located in the water conservation area in the upstream of Mother River of China,which plays a pivotal role in maintaining the pattern of the plateau ecosystem.However,the ecological security of this region is seriously threatened by grassland degradation and desertification.Focusing on a typical area of Zoige Plateau grassland and selecting key indicators of soil aggregate changes,this study quantified the changing trends of soil aggregates and organic carbon during the grassland degradation evolution process.It analyzed the correlation between grassland degradation evolution and changes in soil aggregates and organic carbon on the plateau.
