Geomorphological Characteristics of Bedding Landslides in the Clastic Rock Zone of the Three Gorges Reservoir and Their Implications for Early Identification in the Shazhenxi Region
摘要
The research establishes topographic recognition criteria for four types of bedding landslides in the clastic rock area of the Three Gorges Reservoir region, including groove side boundaries, isolated closed contour lines, linearly distributed gullies, rock walls, cliffs, tensile trough terrain lines, and wavy terrain lines. Using these markers, 38 potential landslides were identified in the Shazhenxi area, of which 27 are already included in the database. These findings indicate that the proposed topographic recognition features are effective for identifying bedding landslides in the region and can reflect the topographic characteristics of historical landslides. The study recommends further field verification and monitoring of the remaining 11 landslides not yet included in the local landslide database. This research provides a scientific basis for the early identification and disaster prevention of bedding landslides in the Three Gorges Reservoir area and similar regions. The established criteria can be applied to identify similar types of landslides in other areas, offering appropriate technical support for geological hazard prevention and mitigation.
