摘　　要：华北山地"距今二、三百万年"的"冰臼"绝大部分位于第四纪河谷内,"距今1～2万年"的"冰川壶穴"位于全新世河谷内,与华北山地地貌演化相矛盾;所谓的"冰川地貌"组合不是真正的地貌组合,而是不同时代、不同成因地貌的混合,因此,华北山地不存在冰臼。所谓的"冰臼"是不同时代、多种成因的壶穴——距今2.50Ma前后的河蚀壶穴,距今10～20ka的雪蚀壶穴,距今10ka以来的溶蚀穴、溶蚀—河蚀壶穴、风化—风蚀壶穴、现代壶穴和水潭。In North China mountain regions, the so-called ＂glacial potholes 2 -3 Ma ago＂ locate mostly now in Quaternary river valleys, and so-called ＂glacial potholes 10 -20 ka ago＂ locate in Holocene river valleys now, which come into conflict with the landform evolution of North China mountain regions. The alleged ＂ glacial landform＂ combinations are not the real ones, but rather the mix of landforms from different periods and origins. So, there are not glacial potholes in North China mountain regions. The so-called ＂glacial potholes＂ are multi- origin potholes of different periods： river-eroding ones about 2.5 Ma ago, snow-eroding ones 10 - 20 ka ago, dissolution ones 10 ka up to now, dissolution and river-eroding ones, weather and wind-eroding ones, modern ones and swags.
