摘　　要：柴达木盆地东、西台吉乃尔盐湖及一里坪盐湖为硫酸镁亚型,是以富锂为特色并伴生硼、钾、镁、溴、碘的自然卤水资源。该区域卤水中赋存的LiCl、B2O3、KCl规模分别为超大型、大型、中型,其潜在的经济价值约为0.28万亿元。目前3个盐湖的开发均通过"卤水开采-盐田滩晒-深加工"3个阶段来提取盐湖卤水中的高价值组分,生产钾肥、碳酸锂、硼酸等。3个盐湖的可开采年限分别为35、32、77a。3个盐湖经过多年的开发,目前存在的主要问题为:盐湖资源的可开采量远低于资源储量,盐田生产资源收率低,资源综合利用率低。针对以上问题提出了盐湖有限资源合理高效利用与协同发展的建议与思考。East-West Ginair and Yiliping Salt Lake in Qaidam Basin are magnesium sulfate subtypes,which are natural brine resources with rich lithium and associated boron,potassium,magnesium,bromine and iodine.The LiCl,B2O3 andKCl occurred in the brine in this region are super large,large and medium in scale respectively,and their potential economic value is about 0.28 trillion yuan.At present,the development of the three salt lakes is through the three stages of " brine mining-solar pan evaporation-deep processing" to extract various high-value components in the brine of the salt lake,respectively producing potash,lithium carbonate and boric acid.The three salt lakes have mining service life of 35,32 and 77 years respectively.The three salt lakes have been developed for many years.Currently,the existing main problems are the recoverable amount of salt lake resources being much lower than the resources reserves,low yield of production resources in solar pan and low comprehensive utilization of resources.Finally,suggestions and thoughts on rational and efficient utilization and coordinated development of the limited resources in the three salt lakes are put forward.
