摘　　要：通过对云南蒋家沟粘性泥石流的野外观测 ,讨论了粘性泥石流残留层的定义特征 ,在大量实测数据基础上 ,分析了残留层易形成时段的特性 ;分别对一次泥石流过程、若干阵泥石流和一阵泥石流残留层的变化进行了相关分析 ;On the basis of observations of viscous debris flows in Jiang ji agou,characteristics of the residue layer are discussed Observation data has re v ealed the stage feature of the formation of residue layer; and variations of res idue layers have been analyzed for many surges in a certain course of debris flo w and for a special surge In the end,reduction of resistance by the residue lay er are discussed using the data

关 键 词：泥石流 残留层 减阻作用 相关分析 观测数据
