摘要: 号称“世界屋脊”的西藏高原,盐湖星罗棋布。据初步统计,该区约有盐湖170多个,面积达6000多平方公里。它是我国盐湖分布最多的地区,同时,也是世界上重要盐湖分布区之一。在盐湖中,除蕴藏着大量的石盐、芒硝、硼酸盐等具有工业价值的固体盐类沉积外,卤水中的钾、镁、硼、锂、铷、铯等元素的含量之高,储量之大,在世界上也是罕见的。全面地考察和研究该区的盐湖,不仅对研究高原的隆起,而且对发展当地工、农、牧业生产皆具有十分重要的意义。本文着重探讨西藏的盐湖分布、物质成分、形成和资源开发利用问题。

Abstract: The Xizang Plateau is an area in which there are many salt lakes andrich in resources.The salt lakes contain nearly forty kinds of chemicalelements and twenty-seven kinds of minerals,especially their high contentand large reserves of boron,lithium and potassium,etc.,which are wellknown to the world.On the basis of analyzing the distribution,the hydrochemical charac-teristics,the salt-forming law of the salt lakes in Xizang plateau,togetherwith the geolgical structure,palaeogeographic environments and the stronghydrothermal activities of the plateau,this article has discussed the condi-tions of the formation of the salt lakes and the mechanism of their genesis.We consider that the block basin was the topographical basis for the fossillakes formed the arid climate was the palaeogeographic environments affe-cting the salinization of lake water and controlling the distribution of saltlakes,and the strong natural hydrothermal circulation has supplied abundantboron,lithium and potassiou,and other materials to the salt lakes.
