摘要
沟道粘性泥石流堆积地貌是造貌流体与底床相互作用下的产物。据沟内堆积地貌部位，将沟道粘性泥石流堆积地貌分为沟内滩和沟口扇（锥）．据造貌流体的宽深比值，将沟内滩分为高位、中位、低位三类沟内滩和沟槽滩；将沟口扇分为地上沟道、溃口扇和满扇滩等。
According to morphogenesis,the target of accumulational landform of viscous debris flow isclassified into 2 stipes.Ⅰ-stipe target is location where viscous debris flow deposited. Hence the landform is classi-fied into mud-gravel flats in the ravine and the fan at the ravine mounth.Ⅱ-stipe target is ratio /H,where B is width of debris flow body, H is depth of debrisflow body. When the rate/H> 10 , it will be over bank flows to deposit into high locationflats or over fan;when rate /H=5-10,it will be overflow and deposit into lateral bank ofdebriS flow;and when rate /H<5,it will be channel flow deposit into middle flats or lowflats and channel flats.Sametimes the flats and the fans may link each other into a handle fan.
