Geological disaster risk assessment is crucial for regional disaster prevention and mitigation, playing a vital role in strengthening natural disaster prevention capabilities. This study focuses on southern Tieling, constructing a comprehensive geological disaster risk assessment system. An AHP-information quantity coupling model is employed, with hydrological slopes as evaluation units. Information quantities of nine susceptibility indicators, including geomorphology, geological structures, and vegetation hydrology, are calculated. Hazard assessment is conducted by synthesizing weighted inducing factors, which are then integrated with data on disaster-bearing elements like population, buildings, and roads. Risk zoning is determined using a risk matrix. Results indicate that high-risk geological disaster areas are mainly distributed east of the line connecting Pingdingpu, Xiongguantun, and Yaopu towns, characterized by steep slopes and significant topographic relief. Notably, all disaster points are located within high-risk zones. These findings provide essential support for disaster management, and territorial spatial planning, and offer valuable insights for infrastructure development and social planning in southern Tieling.
