| 摘 要： | 根据黄河托克托段格尔图营剖面的沉积记录，对于其湖相沉积的时代和易溶盐含量作了初步分析，认为它是存在于早、中更新世时期的微咸－半咸水湖，尤其是其消亡前期成为典型的半咸水湖，说明当时湖泊为半干旱地区的内陆湖。在中更新世中晚期时，此内陆湖切穿，沟通形成现在之黄河河道。该剖面建立的意义在于提供黄河土黩特古湖性质证据，并初步建立了内蒙古高原的“泥河弯层”剖面。

| Abstract: | Based on the deposits record of Gertuying profile where are at the Tuoketuo section of Yellow River,the deposit's forming time and readily soluble salt are analysised in the paper.It is regarded that the Tuoketuo palaeo-lake was being in the Early and Middle stage of Pleistocene and was a micro-salt or semi-salt water lake.Further more,it was a in-land lake which was at semi arid land area.In the middle pleistocene,the palaeo-lake was cut over and was forming to be a section of river-Yellow River. |

| Keywords: | palaeo-lake deposit the upper and middle reaches of Yellow River the early and middle stage of Pleistocene |
