摘要
根据萨拉乌苏河若干地段的第四纪沉积记录,讨论了萨拉乌苏河河谷的形成时代、古湖形成原因、全新世湖沼层的环境意义、晚更新世黄土与风成砂关系等问题,认为萨拉乌苏河地区所经历的河流—湖泊—湖沼—河流的演化过程,均受到第四纪环境演变规律的控制,是自然环境变迁的结果.
Accoding to the sediment profiles of Sjara Osso-Gol river in Quaternary period, the forming time of the valley of Sjara Osso-Gol river and the origin of Sjara Osso-Gol paleolake and the environment meaning of limnetic layer in Holocene epoch are studied. It is stated that tile cvolation of the paleolake and river is controled by the development of natural environment in Northern China.
