摘　　要：以西藏查波措盐湖湖水作为研究对象,依据15℃下Na^+、K^+、Mg^(2+)//Cl^-、SO_4^(2-)-H_2O五元相图,研究了高温蒸发后再冷却至15℃过程中湖水的析盐规律,同时获得了湖水组成、体积及蒸发量等的变化规律,为盐田规划设计、指导现场生产操作提供了依据.The object of the research is the brine in Chabocuo Salt Lake of Tibetan Plateau. According to the quinary metastable phase diagram of Na＋, K＋, Mg2＋//C1-, SO2-4-H20 , the crystallization law of the salts from the brine was studied through the process of 15 ℃ normal temperature evaporation. At the same time, data about the composition and volume of the brine, as well as the evaperation rate were obtained. All this can provide important imformation for the programming and designing of salt fields and production on the spot.
