摘要：

Based on detailed field data from recent geohazards surveys in the Loess Plateau region of western China, this study analyzes the key factors that control loess landslides. The evolution phase of river valleys, the geological structure of slopes and the geometry of slopes are all found to play a role in determining the occurrence, distribution and other characteristics of loess landslides. Groundwater and vegetation also contribute to their formation. A combination of human engineering activities and precipitation events are the principal triggering factors for the instability of loess slopes.
