现代的大兴安岭地貌骨架是由燕山、喜马拉雅山造山运动及新构造运动造成的。在晚白垩纪到第三纪初,地壳相对稳定,经历了一个全面准平原化时期,现时广泛分布的浑圓平顶山巔,就是当时的准平原面,伴之而来的垂直上升和长期以来的侵蚀——剥蚀作用,形成了现代地貌之轮廓。第四纪冰期与间冰期的存在及火山的喷发,对现代地貌与成土母质也带来了明显影响。在新构造运动的影响下,大兴安岭迄今仍有上升趋势,侵蚀作用仍在进行,但由于植被生长繁茂,对侵蚀作用有一定的抑制。大兴安岭山地是古老的褶皱断块山。基
The modern Daxinganling landform skeleton is caused by Yanshan, Himalayan orogeny and neotectonic movement. During the Late Cretaceous to the beginning of the Tertiary, the crust was relatively stable and underwent a period of complete quasi-plastification. Nowadays, the vast and flat top of the Pingdingshan is the quasi-plains, with the accompanying vertical rise and long-term Erosion - erosion, forming the contour of the modern landscape. Quaternary glacial and interglacial existence and volcanic eruptions have also had a significant impact on modern landscapes and soil parent materials. Under the influence of neotectonic movement, there is still an upward trend in Daxinganling so far. The erosion is still underway. However, due to the lush growth of vegetation, there is some inhibition to erosion. Daxinganling Mountains is ancient fold fault block mountain. base
