摘　　要：吉兰泰盐湖区是内蒙古干旱区内一个具有代表性的地区。本文在分析吉兰泰地区第四纪以来对称性空间地貌结构和特征以及沉积相的基础上,指出吉兰泰湖泊的演化,经历了从古大湖—古大湖分解—形成新内陆湖的持续收缩过程。通过与青藏、新疆和内蒙古等高原湖泊演化的对比研究。证明吉兰泰湖泊的发育明显受到新构造运动和宏观气候因素的综合控制。现代人为活动影响也十分强烈。The area of the Jilantai saline lake is a typical arid region in InnerMongolia.The paper is based on the structure and the feature of symmetricalgeomorphy and sedimentary facies in the Jilantai area since the OuaternaryPeriod. It shows the whole process of evolution and sustained contractionof Jilantai lakes: the formation of the ancient lake, the decomposition of theancient lake and the formation of the new continental lake. Meanwhile,the paper,through comparative studies on the evolution ofsome highland lakes in Qinghai, Tibet, Xinjing and Inner Mongolia, provesthat the development of Jilantai lakes is obviously controled by the factorsof new tectonic movement, the macrolimate as well as the artificial effectby modern man.
