应用云南东川蒋家沟泥石流输沙时序资料，重构了高频率暴雨泥石流输沙年际变率的旋回现象，即周期性，并分析了其周期性变化的成因，为暴雨泥石流灾害的预测研究探索了一条新路．
Based on the data of sediment transport in Jiangjiagou, Dongchuan, Yunnan, the cyclone of interannual variability of sediment transport in high-frequency heavy rainstorms is reconstructed, that is, the periodicity. The causes of cyclical changes are analyzed, which are the prediction of the debris flow disaster Research explored a new road.
