There are several saltworks in China.

Luchang Yantian: It is the largest Yantian in China, mainly distributed along the coasts of Hebei, Tianjin and Bohai, among which Tanggu Yantian is the largest, with an annual output of1190,000 tons. Luchang Yantian starts from Huanghua in the south and reaches Shanhaiguan in the north, including Tanggu, Hangu, Dagu, Nanbao and Daqing River, with a total length of 370 kilometers.

Bag saltworks: The largest saltworks in Taiwan Province Province, located on the southwest coast of Taiwan Province Island, where the beaches are straight and the terrain is gentle and inclined. It is dry and rainy for half a year in winter, and it often doesn't rain for two or three months, with abundant sunshine and strong monsoon, which is very conducive to drying sea salt. It is the only ideal coastal area for drying sea salt in Taiwan Province Province.

Ying Ge Yantian: The largest Yantian in Hainan Province, with many coastal ports and beaches on Hainan Island, is an ideal natural salt drying place. There were six saltworks in Ming Dynasty, such as Awakening and Le Hui. In the Qing Dynasty, there was a saltworks in Sanya Port, and later new saltworks such as Yaxian, Lingshui, Danxian and Lingao appeared.

Formation conditions of saltworks

Formation conditions of salt field: climate with less precipitation and large evaporation; Wide, flat muddy beaches; For seawater with high salinity and good water quality, the location conditions for the formation of Yantian are: climate: high temperature, less precipitation, strong wind and strong sunshine: favorable for evaporation; Terrain: The beach is flat, the coast is muddy and the area is vast.

There are three salt fields in China, namely Luchang Salt Field, Bag Salt Field and Ying Ge Sea Salt Field. Lu Yan Salt Field is located in the Bohai Sea coast of Hebei and Tianjin, Baoyan Salt Field is located in the southwest coast of Taiwan Province Island, and Ying Ge Haiyan Field is located in the southwest coast of Ledong County, Hainan Province, mainly producing edible salt and industrial salt.

Luchang Salt Field is the largest salt field in China, accounting for a quarter of the total sea salt production in China. The distribution of Luchang salt field is influenced by both topography and climate. Luchang Yantian is located in the west bank of Bohai Bay, and the natural conditions for drying salt are superior: there are long, wide and flat mudflats, which are conducive to seawater evaporation. This is a rainy season with rapid temperature rise and severe evaporation in short spring.
