处于欧亚大陆东南部的中国由于纬度较低和大陆性气侯的影响,冰期中冰川的规模是有限的。但是,已有的事实说明,冰期气侯仍然在中国的自然环境上打下了深刻的烙印。在中国西部高山和高原地区的若干地点,已经查明有不少于四次冰期的古冰川遗迹,全新世冰期的冰川前进也得到证实。在中国东部地区,是否有过第四纪冰川活动及当时冰川规模有多大至今仍在讨论之中,但冰期气侯的影响,特别是晚更新世冰期中寒冷环境的影响是很强烈的。另外,七十年代青藏高原的科学考察说明,高原在第四纪期间的隆升既为冰川发育创造了有利的地势条件,而这种隆升促进了亚洲大陆季风的形成,决定性地改变了整个中国的自然环境。这是研究中国第四纪应当特别注意的问题。
China, southeastern Eurasia, has limited glacier scale during the glacial period due to the effects of low latitude and continental climate. However, the existing facts show that the climatic climate still lays a profound imprint on China’s natural environment. At several sites in the western mountains and plateau of western China, ancient glaciers have been identified with not less than four glacial stages, and the glacier advance during the Holocene glaciation has also been confirmed. Whether or not Quaternary glaciers have been active in the eastern part of China and the extent of glaciers at that time are still under discussion. However, the climatic effects of the ice age, especially the cold environment during the Late Pleistocene glaciation, are very strong. In addition, the scientific investigation of the Qinghai-Tibet Plateau in the 1970s shows that the uplifting of Plateau during the Quaternary created favorable conditions for the development of glaciers, and this uplift promoted the formation of the Asian monsoon and decisively changed the entire China’s natural environment. This is a question that should be paid special attention to in studying Quaternary in China.
