An Integrated Multi-Technology Configuration Method for Ecological Hazard Prevention and Control in Geologically Disturbed Areas. Earth Science, 51(9): 3290-3308. doi: 10.3799/dqkx.2026.304 |
To address technology-environment mismatch, fragmented implementation of individual measures, and insufficient basis for technology adaptation in the ecological prevention and control of hazards in geologically disturbed areas, an integrated multi-technology configuration method is developed. Based on the coupling relationships among the engineering, hazard, ecological, and geological subsystems, a framework for scenario attribute identification and eco-geological environmental problem diagnosis is established. According to their dominant functions, treatment technologies are classified into six technical units: mechanical reinforcement, hydrothermal regulation, soil improvement, vegetation restoration, landscape integration, and water-fertilizer supply. Subject to safety redlines and engineering applicability constraints, candidate technologies within each technical unit are evaluated for suitability using combined weighting and comprehensive scoring methods, and multi-technology configuration schemes are generated according to prerequisite dependencies, functional complementarity, compatibility, and potential conflicts among the technical units. A large post-earthquake collapse deposit in Jiuzhaigou is taken as a case study. Under the combined constraints of intense rainfall disturbance, steep and loose deposits, coarse and infertile substrates, and high landscape sensitivity, a configuration scheme centered on local slope stabilization, soil and water process regulation, soil habitat reconstruction, near-natural vegetation restoration, and targeted maintenance is developed. The proposed method can transform ecological prevention and control technology selection from experience-based judgment to systematic adaptation under scenario constraints, thereby providing methodological support for technology configuration in the ecological treatment of hazards in complex geologically disturbed areas.
