青藏高原盐湖的形成与分布

青藏高原是现代盐湖最发育的地区之一.盐湖集中分布于干燥度很大的羌塘和柴达木盆地两地区.这些高原地区具备成盐的优良条件:1.受断陷控制的封闭性内陆湖盆;2.晚更新世一现代持续的干旱气候;3.富含成盐元素的各种天然水流,特别是富含硼、锂、铷、铯等的地下热水的长期补给.这些条件决定着盐湖的规律性分布.

The origin and distribution of salt lakes in qinghai-xizang plateau

Qinghai-Xizang plateau is one of the most developmental incdern salt lake regions in the world. The salt lake are distributed mainly in the two districts with a high aridity-Northern Xizang and the Qaidam Basin. This plateau possesses the following excellent conditions for salification;1, the enclosed inland lake basin controlled by the subsidence of the fault;2, a sustained dry clinatc irora late pleistocene to ths presnt;3, a long-term supply for various natural water flows rich in salifiable ements, especially the ground thermal water flows rich in B, Li, Rh, Cs etc. These conditions are the dicisive factors for the regular distribution of the salt lakes.
