| 摘 要： | 我国东部中低山区第四纪冰川的存在与否一直存在争议,但冰川必然对山体进行冰蚀作用形成冰蚀地貌。为了分析我国东部中低山区的山体地貌是否具有冰蚀特征,该文选取了现代冰川集中发育区-喜马拉雅山脉作为冰蚀地貌的研究对象,通过宏观分析,除了由缩口、三角脊、残弧组成的冰斗系统外,还发现冰蚀作用过程存在避谷、吞脊、切壁、穿梁等特殊习性。分析认为冰蚀过程主要受制于雪线高程、积雪高程与坡向坡角三方面因素的控制。以此为基础,对我国东部的江西庐山、山东蒙山、大兴安岭主峰黄岗梁三个地区的山体地貌进行对比分析,发现这些山区的山体地貌与喜马拉雅山脉的冰蚀地貌具有一致性。文章从冰蚀过程的角度确认了我国东部中低山区存在第四纪冰川的事实。

| Abstract: | It is controversial whether Quaternary glaciers has existed in the middle and low mountains of eastern China,but the glacial erosion landforms must be formed through ice erosion.In order to analyze whether the mountain geomorphology has the characteristics of the ice erosion in these areas.The Himalayas where develops widespreadly modern glaciers is selected as the research object.Through macro analysis,the glacial cirque system composed of necking,triangular ridge,residual arc as well as some particular characters in the process of ice erosion like valley avoidance,swallowing ridge,cutting wall and penetrating beam.It is considered that ice erosion process is mainly controlled by three factors:snow line elevation,snowpack elevation and slop direction and angle.On this basis,It is found that the mountain landforms in eastern China including Lushan in Jiangxi province,Mengshan in Shandong province,Huanggangliang,the main peak of Greater Khingan are consistent with the ice erosion landforms of the Himalayas using comparative analysis.From the glacial erosion process,It can be confirmed that Quaternary glaciers exist in the middle and low mountains of eastern China. |
