摘　　要：通过实地考察腰店河流域古泥石流残留台地的沉积构造,分析泥石流的形成原因,详细描述泥石流堆积物的沉积特征.结合泥石流容重计算方法和泥石流堆积物的颗粒分析实验结果,计算出泥石流活跃期的天然容重,确定泥石流类型.最后讨论了泥石流的形成机制、变化趋势以及对人类活动的影响.Based on field survey of the sedimentary structures of ancient debris flows in Yaodian valley, we analyzed the causes and described the sedimentary characteristics. Then the natural density of debris flow activity was calculated using the gravel and fine particle content of ancient debris flows＇ samples in different spots to define the type. Finally the formation mechanism of debris flows, and the impact to human activities were discussed.
