Mechanism analysis underlying soil erosion resistance of accumulation bodies under different restoration modes in Jiuzhaigou
摘要
Abstract
[Objective]This study aims to investigate the underlying causes for differences in soil erosion resistance of accumulation bodies under different restoration modes in Jiuzhaigou,providing a scientific basis for ecological prevention and control of such bodies.[Methods]Taking Jiuzhaigou as the study area,accumulation bodies under four restoration modes with similar restoration durations were selected as the primary research objects.Through field surveys and laboratory experiments,soil erodibility indicators across different bodies were comprehensively compared,and a structural equation model(SEM)was applied to explore the mechanisms of soil erosion resistance.[Results](1)Soil erodibility(K values)under different restoration modes followed the order:natural restoration>geological disaster control>comprehensive management>soil and water conservation.(2)The SEM results indicated that the combinations of directly influencing factors differed among various accumulation bodies,while particle composition consistently acted as a key factor across all restoration modes.[Conclusion]Among the four restoration modes,soil and water conservation demonstrates the most significant effect in improving soil erosion resistance,followed by comprehensive management,whereas geological hazard control and natural restoration show relatively weaker effects.关键词
