Research Progress and Paradigm Evolution in Talus Slope Geomorphology: A Bibliometric Analysis Based on Web of Science

Talus slopes and scree deposits connect rockwall sediment supply, gravitational transport, footslope storage, hydrothermal conditions, and mountain hazards, yet their literature is distributed across several disciplines. This study develops a manually refined bibliometric dataset to clarify the knowledge structure and thematic evolution of talus slope geomorphology. We retrieved 971 records from the Web of Science (WoS) Core Collection, including the Science Citation Index-Expanded (SCI-EXPANDED) and Social Science Citation Index (SSCI) databases, manually screened their geomorphic relevance, excluded records from the incomplete publication year 2026, and analyzed 548 articles and reviews published during 1966–2025. Bibliometrix and Biblioshiny analyses show sustained publication growth, especially after 2006, and an intellectual base combining slope-process geomorphology, paraglacial and periglacial research, geophysical investigation, and hazard studies. Standardized Author Keywords indicate increasing attention to permafrost environment, subsurface detection, multi-source monitoring, and slope hazards. These indexed patterns support a synthesis of talus slopes as dynamic source-transport-storage systems, while the WoS-only coverage and manual refinement steps define the study’s evidential limits.
