Chaerhan salt lake is located in the south of qaidam basin. Elevation 2670 meters, about 60 kilometers south from golmud, north to the big ChaiDan 110 kilometers. More than 40 kilometers wide north and south, something more than 140 kilometers long, the total area is 5800 square kilometers. It is four salt lake area of qaidam in the largest and the most abundant reserves, is China's largest natural salt lake, ranked second in the world.

Chaerhan salt lake, is a potassium is given priority to, associated have magnesium, sodium, lithium, boron, iodine and so on many kinds of minerals inland large comprehensive salt lake. It has a very rich potassium magnesium resources, its reserves of 50 billion tons, is our country main producing area of potassium magnesian salt.

Chaerhan salt lake, it is located in the gobi desert, the climate is hot and dry. Due to a long period of young, much lower than the evaporation and rainfall, lake high levels of brine is gradually into YanLi crystallization, especially the salt lake surface is form 1-2 meters, and even 3-4 meters thick salt cover, and exceptionally hard. The salt cover carrying capacity is very big, car, train can run on it, the plane can rise and fall on it, even on it, and build the house building a factory. The famous qinghai-tibet railway, highway and case, China's largest JiaFeiChang ChaErHan JiaFeiChang, are built on chaerhan salt lake on.

Chaerhan salt lake flat terrain around vast, specific scenery. The lake is like a field of newly cultivation of land asked, and without a strain on the grass. Sunny, the vast expanse of the lake, steam rising, shiny wave, like a sea of blue waves is all, sometimes even still appear changeable "mirage", people can see the lake since long continuous flashes of 座座 mountain peaks, woods linhai, or ZhuangZhuang tall buildings. Salt lake has the salt bridge, the salt sea YuBo landscape.

Chaerhan salt lake is four salt lake in qaidam development later one, but it is one of the biggest development scale. The early 1950 s, people in chaerhan salt lake build on China's first a salt highway bridge. 50 s, from all sides in the builders of the drought of vast salt lake lowest-tax jurisdictions, with the first batch of potash production method. Later, after nearly 30 years in the large-scale development of construction, a China's largest, the annual output of 1 million tons of large JiaFeiChang first phase of the project has been completed, and it can produce high quality 200000 tons of potash. To adapt to this and other facilities in the lake stands up. In the near future, chaerhan salt lake will become a chemical qaidam city.
