Salt lake resources
Chaerhan salt lake located in the chaidamu Basin Qinghai western chaidamu Basin is the biggest salt lake in china, one of most famous interior salt lakes in the world, apart from Xining 750 kilometers. The salt lake east and west long more than 160 kilometers, north and south extend 20-40 kilometers thick, the salt deposit approximately are 2-20 meters, the area about 5800 square kilometers, the elevation 2670 meters. the lake is preserving 50,000,000,000 tons above sodium chloride, may supply the world human edible in 1000 year. Chaerhan salt lake is the biggest potassium magnesium salt deposit in china, one of large-scale salt lake ore deposits in the world, i the lake is containing the quite rich resources and so on potassium, sodium, magnesium, lithium, boron, bromine, iodine, the ultimate reserves more than 600 hundred million tons, the magnesium chloride reserves surpasses 3,000,000,000 tons, comes first of nation, occupies the national magnesium resources 74%.

Formation
“Chaerhan” is Mongolian, the mean is “the salina”. The saline lake is situated at the Gobi desert, here climate burning hot dry, the sunshine time is long, the moisture transpiration rate is higher than the precipitation by far. Because the long-term windblown and sunburnt, in the lake has then formed the highly concentrated bittern, crystallized the salt particle gradually, the level of the lake hardened the thick salty lid, was exceptionally hard. around the saline lake the topography is smooth, wilderness is boundless, but the scenery is unusual. The entire level of the lake is a piece just had done farm work the fertile soil probably, is also the scale likely, a wave. It is a pity on the land have not green grass, in the lake water not tours the fish, in the sky does not have the bird, a silence. When glorious weather, the vast level of the lake is similar to a giant valuable mirror, emits the silver ray, steaming hot, the wave light twinkle, like ocean If you fortunately, will also see unpredictable “mirage”, will make one be in trance.

There are many flower on the salina, crystal and clear , differ in thousands of ways, some look like the coral, the pagoda, the flowers, some look like the constellation, the ivory, the gem, makes one be unable to put down, praises without cease, is honored as the blue color the flower. Places oneself in the flowering shrubs, causes the person daydream to be boundless, roams as if in the fairyland. In the lake also produces is honored as “king of the saline lake” the pearl salt, pure white like snow, grain of bright and clean like jade.

Equipment of factory 
 In the lake already constructed the Chinese greatest annual production 1,000,000 ton Qinghai potassium fertilizer factory. What is incredible is in the saline lake also some long 32 kilometer roads and railroad going through, is one floats on the bittern “ten thousand feet of salt bridge”, the road and the railroad contain geermu to Dunhuang and Qinghai-Tibet railway's section
