摘　　要：小相岭地处横断山脉东缘,确切分布着第四纪冰川遗址。冰斗位于冰川的源头,研究冰斗的发育特征对于研究整条冰川具有重要意义。通过对小相岭冰斗的坡向和朝向、冰斗形态以及冰斗分布海拔高度的研究,表明:西坡冰斗分布明显多于东坡,W方向上的冰斗分布最多,N、S方向上分布最少,且小相岭地区大部分冰斗为长形或者宽形冰斗,而圆形冰斗所占比例较少,在三级冰斗中,3953~4434 m海拔高度上冰斗分布数量最多,最适宜冰斗发育。Xiaoxiangling is located at the eastern edge of Hengduan Mountains,where quaternary glacial sites are located.The ice bucket is located at the source of the glacier.It is of great significance to study the development characteristics of the ice bucket.Phase through to the small ridge cirque slope to form and the ice bucket,ice bucket,direction and distribution of the elevation of research,showed that go significantly greater than dongpo cirque distribution,distribution of W in the direction of cirque,most distribution at least N,S direction,and a small ridge area most ice bucket for long or wide cirque,however,the proportion of circular cirque in level 3 ice bucket,ice bucket on 3953~4434 m above sea level distribution of the largest number,the most suitable cirque development.
