摘要
通过大范围的野外考察,结合大尺度的航片资料,在总结前人研究成果的基础上,提出冰川作用是大湖盆地地貌形成的首要要素。在末次盛冰期的巨大冰川的机械侵蚀和磨蚀作用下形成现有巨大盆地。随着气温的上升,冰川侵蚀和移动,导致盆地内留下鼓丘、冰碛台地、蛇形丘、冰碛丘陵等冰川地貌。同时冰雪融水,使诸多小自盆地积水成湖,构成串珠状的湖泊分布格局。
Based on the field investigation and aerophotography data, it is thought that glaciation is the essential fac- tor for landform formation of Great Lake Basin. The giant basin had formed by mechanical erosion and abrasion of giant glacier in the last glacial maximum. With raising of temperature, glacier eroded and moved, which caused drumlin, moraine platform, esker and moraine hill to appear in basin. Meanwhile, the melt water caused many small basins to form lake with moniliform distribution pattern.
