冰川地貌是地貌研究的重要组成部分,研究阿拉斯加中南部的冰川地貌有助于进一步了解中南阿拉斯加的地貌景观。在梳理一系列冰川地貌特征以及成因的基础上,对阿拉斯加中南部地区的冰川地貌进行了分析。指出冰川地貌可以划分为两种类型:冰川刮擦山体后所形成的冰川侵蚀地貌和冰川经过低地时倾倒刮带山体碎屑后所形成的冰川沉积地貌。阿拉斯加中南部地区冰川侵蚀地貌形态有U形山谷、冰斗、峡湾、磨光面、羊背石、冰蚀槽、冰川擦痕等;冰川沉积地貌有冰川漂砾、冰碛物、蛇形丘、鼓丘、锅形湖群、堰塞湖等。
Glacier landform is an important part of geomorphology research. Studying the glacier landform in south-central Alaska helps to understand the landscape of Alaska in Central South China. Based on a series of glacial landform features and their causes, glacial landforms in central-southern Alaska are analyzed. It is pointed out that the glacier landform can be divided into two types: the glacial erosion landform formed by the glacier scraping the mountain and the glacial sedimentary landform caused by the dumped scraping belt mountain debris in the glacier. Glacier erosion topography in central and southern Alaska includes U-shaped valleys, ice buckets, fjords, polished surfaces, goat backs, glacial troughs, glaciers scratches, etc .; glacial sedimentary features are glacial boulders, moraines, snakes Mound, drum hill, pot-shaped lake group, dammed lake.
