摘要

摘要: 本研究针对青藏高原TBM洞渣边坡结构松散、养分贫乏和植被恢复困难等问题，评价植物-微生物联合修复对边坡固土抗蚀的作用。采用室内盆栽和野外边坡试验，设置对照(CK)及枯草芽孢杆菌(K)、地衣芽孢杆菌(DY)、解淀粉芽孢杆菌(JD)、黑曲霉(H)、哈茨木霉(HC)处理，测定养分、酶活、植物生长和坡面水动力指标。研究表明：植物-微生物联合处理通过促进根系发育、提高酶活和改善养分条件，对坡面水动力特征产生综合影响，从而提升边坡抗侵蚀能力。径流功率最大削减97.36%，阻力系数最大增幅486.26%。为高寒高海拔山区TBM弃渣体边坡的生态修复与水土保持提供了有效的技术方案。

Abstract: This study aimed to evaluate the effects of plant-microbe combined remediation on soil stabilization and erosion resistance of TBM muck slopes on the Qinghai-Tibet Plateau, where slope materials are loose in structure, deficient in nutrients, and difficult to revegetate. Indoor pot experiments and field slope trials were conducted. A control (CK) and five microbial treatments were established, including Bacillus subtilis (K), Bacillus licheniformis (DY), Bacillus amyloliquefaciens (JD), Aspergillus niger (H), and Trichoderma harzianum (HC). Soil nutrients, enzyme activities, plant growth, and slope hydrodynamic parameters were measured. The results showed that the plant-microbe combined treatments improved root development, enhanced enzyme activities, and ameliorated nutrient conditions, thereby exerting integrated effects on slope hydrodynamic characteristics and ultimately increasing slope erosion resistance. Runoff power was reduced by up to 97.36%, while the resistance coefficient increased by up to 486.26%. (Conclusion) These findings provide an effective technical approach for the ecological restoration and soil and water conservation of TBM waste-muck slopes in alpine and high-altitude regions.
