日本是个岛国,地势较低,形成冰川的条件较少。现在虽然没有达到雪线以上高度的高山,但在第四纪冰期确实有一些山地在雪线以上。以保存到今天的冰斗底高度来看,第四纪冰期的雪线高度在北、中日本阿尔卑斯为2,600米、南日本阿尔卑斯为2,900 Japan is an island nation with low terrain and less glacier conditions. Although there are no high mountains above the snowline, there are indeed some mountains above the snow line during the Quaternary ice age. In keeping with the height of today’s ice bucket base, the snow line height in the Quaternary Ice Age is north, 2,600 meters in the Central Japan and the Alps, and 2,900 in the South Japan Alps
