试论吉兰泰盐湖的发育与资源保护问题

位于包头－吉兰泰断陷盆地西南部的吉兰泰盐湖，其发育过程大体经历了外泄湖、内陆湖与盐湖三个阶段。目前盐湖已发育为干盐湖，并有快速发展为沙下湖之趋势。湖盐开采中出现的晶间卤水水位下降、流沙入湖等问题既是盐湖演化的必然结果，又与开发中轻视资源保护有关。解决这些问题的办法是在顺应盐湖演化规律的基础上采取人工措施，延缓盐湖演化的速度，在盐湖演化为沙下湖之前完成全部采盐任务。

A TRIAL DISCUSSION ON THE DEVELOPMENT AND PROTECTION OF THE JILANTAI SALT LAKE

The Jilantai Salt Lake,located in the southwestern part of the Baotou-Jilantai Sunk Basin,has undergone three stages,that is,flowout lake,inland lake and salt lake.It has developed into dry salt lake stage and is tending towards the sand covered lake.In the exploitation of the salt lake,the stage of intercrystalline brine falls,sand is blown into the lake,all of these kinds of problems result from the evolution of the lake and related to the neglect of protecting resources.Man made measures must be taken to tackle these problems,to manage to postpone the evolution of the lake and to complete the exloitation task before it completely becomes sand covered lake.
