| 摘 要： | To reveal the gravitational erosion process in the headstream area of Jiangjia Ravine, continuous observation was conducted duing the rainy season. The observation and research show that the change of water content of the bank slope lags the precipitation process, the infiltration water con centrates mainly in the shallow layer of the bank slope, also the bank slope was unsaturated, the floods and debris flows in the gully down cut the gully bed, and scour the foot of the bank slope. These results in many collapses, which is the main type of gravitational erosion process, and it provides large amounts of loose solid materials for the eruption of debris flows.
