摘要： 根据大量野外调查,讨论了"三高两低"地形与玛瑙滩玉泉河谷主冰流的存在,分析了带有冰川侵蚀历史烙印的冰缘分布特征,认为不同剖面类型组合的特征差异既体现了冰缘地貌在发生学上的内在联系,更反映出受冰川侵蚀影响造成的迎冰坡与背水坡的差异.

Abstract: Based on numerous field investigations,the authors confirmed the glaciational history of the ice stream flowing from northwest to southeast during the last glaciation.According to a large number of glacial till and erosive traces,as well as different sloping characteristics on Unnamed Island,the topography of"three high and two low",and the existence of the main ice stream in Manaotan-Yuquanhe Valley are discussed.The distribution characteristics of periglacial geomorphology which possesses the historical brand of glacial erosion are analyzed.The characteristic difference of typical combinations in different slopes indicates an inner relationship of its genesis in periglacial geomorphology,reflects an important difference between the front slope and the back slope,which was produced by glacial erosion.
