The Primary Opinion on the Formation Mechanisms of Megadunes and Lakes in the Badain Jaran Desert

摘要: 巴丹吉林沙漠以湖泊众多和沙山高大而闻名于世.到目前为止, 关于湖泊和沙山的成因问题尚存在不同的观点.实际上, 巴丹吉林沙漠湖泊和沙山的形成与该地区地下水的循环交替问题直接相关.参照前人研究成果, 结合开展的巴丹吉林沙漠水文地质调查, 探讨了湖泊和沙山的形成问题, 初步认为巴丹吉林沙漠湖泊主要接受来自东部雅布赖山区区域地下水侧向补给和沙山地下水补给而形成; 高大沙山的形成与降水和地下水关系密切; 高大沙山与湖泊的形成和共存关系是先有沙山, 而后才形成湖泊, 沙山是形成巴丹吉林沙漠湖泊的必备条件.Abstract: Badain Jaran desert is well-known for its distribution of many megadunes and lakes. However, opinions about the formation of these megadunes and lakes vary from person to person until recently. Actually, their formation is directly related to the circulation and alternation of the groundwater in this area. According to the previous research, combining with the current hydro-geological investigation in the study area, this article discusses the formation mechanisms of megadunes and lakes in Badain Jaran desert. It is found that lakes in the desert formed mainly as a result of the lateral recharge of groundwater both from Yabulai Mountain and megadunes. The formation of megadunes is closely related with the rainfall and groundwater in the area. The formation and coexistent relationship between megadunes and lakes are as follows: the megadunes formed firstly, and then the lakes appeared. That means megadunes are a necessary condition for the formation of lakes there.
