Abstract: In accordance with the observed data series, a research and analysis concerning the temporal features of sediment yield of debris flow per year in the Jiangjia Gully watershed has been discussed. Then a preliminarily conclusion is drawn that the peak value of debris flow sediment yield per year experiences periodicity of 6 years. Following this, here come some qualitative reasons and historical cases to identify this conclusion. A sketchy predication, based on this trend, and attempting to describe the trend of sediment yield of debris flow in the watershed in the coming decades, has been presented.
