| 英文摘要 | Root systems play a critical role in soil stabilization, particularly in hillsides prone to erosion and mechanical stress. This study investigates the species-specific effects of root length and weight density on soil cohesion and internal friction angle across different soil depths for Amorpha fruticosa Linn., Lespedeza bicolor Turcz., and Swida alba Opiz. in forest ecosystems of northeastern China. Using the shear strength test and root density test, we analyzed the response of root-soil complex at different soil depths. The results revealed that the Amorpha fruticosa Linn. exhibited the highest soil cohesion at both soil layers, with significantly greater root density compared to the Lespedeza bicolor Turcz. and Swida alba Opiz. The deeper root penetration and denser root network enhanced root-soil complex stability by improving soil cohesion, but not by improving internal friction angle. Our findings provide quantitative evidence of how species-specific root density parameters, enhance soil cohesion at varying depths. The root morphology of Amorpha fruticosa Linn. was shown to be most effective in hillside stability. These insights facilitate our understanding of the mechanisms of root-soil interactions and provide a more comprehensive perspective into soil conservation and ecological restoration efforts in forest areas. |
