| 摘 要： | 从全新世以来湖泊地貌特征入手,结合~(14)C年代数据,探讨了湖泊退缩演化的基本规律和程序:全新世湖泊演化历经早期的大湖时期,中期的分离时期和晚期的继续收缩时期。指出达来诺尔湖群的演化,明显受气候干旱化趋势的控制和影响,在我国北方高原区域内具有一定的可比性,并确定了各时期湖泊演化的基本参数。

| Abstract: | Dalairuoer area is one of the typical areas in the eastern part of Neim- enggu Plateau where the landscape of lakes develops quite well. According to their geomorphic characterisitics and the data of ~(14)C dating, this paper stud- ies the basic law and process of the evolution of the lakes retreat since the Holocene. The evolution underwent three periods; the early period of large lakes, the middle period when the lakes separate, and the late period when the lakes continued to shrink. The evolution of lakes in Dalairuoer area was controlled and influenced clearly by the climatic trend of droughs which can be used as the fundamental parameters to divide the whole period of evolu- tion, comparison with the other evolutions in the plateau region in North China is made. |
