| 摘 要： | 据成因,把泥石流堆积地貌分为自然堆积地貌和人为堆积地貌。据堆积过程,把自然泥石流堆积地貌分为古泥石流台地、老泥石流台地和近代泥石流长柄扇。据建筑物引起的堆积形态,把人为堆积地貌分为泥石流堆积扇(锥)、回淤泥砾滩、侧积泥砾堤和堰塞洼地。

| Abstract: | Based on the field investigations, classification of accumulationsl landforms in Jiangjia Ravine is made in this paper. According to the genesis,the accumulational landform of debris flow may be classified into natural and man-made ones. According to the accumulated processes, the natural accumulational landform may be classified into paleo-platform of debris flow(Q3),old platform of debris flow(Q4)and recent fan with long handle(before 1000 years). The man-made accumulational landforms may be classified into fan of levee tail,fan (cone) of branch gully, mud-gravel beach for bach deposit,mud-gravel dyke for side deposit and barrier depression. The accumulational landforms of debris flow will induce the deposit conditions to changed Therefore, the deposit conditions may be improved due to rational distribution of the construction. |
