Luchang Salt Field is the largest salt field in China, accounting for a quarter of the total sea salt production in China.
Mainly distributed in the Bohai Sea coast of Hebei Province and Tianjin. Tanggu Salt Field is the largest, with an annual output of1190,000 tons. From Huanghua in the south to Shanhaiguan in the north, it includes salt fields such as Tanggu, Hangu, Dagu, Nanpu and Daqing River, with a total length of 370 kilometers, more than 2.3 million mu of salt fields, with an annual output of more than 3 million tons of sea salt, accounting for a quarter of the total national sea salt output.
Reasons for the formation of Luchang Yantian: The distribution of Yantian is influenced by topography and climate. Luchang Salt Field is located on the west bank of Bohai Bay. Because of this superior natural condition of drying salt: 1. There are long, wide and flat muddy beaches. 2。 Weather conducive to seawater evaporation, this is a short rainy season, and the temperature rises rapidly in spring, and evaporation is vigorous.
Conditions: flat terrain and wide beach; It's windy and rainy, with plenty of sunshine and strong evaporation.
Luchang salt area has a long history of development. As early as the Ming Dynasty, Luchang Town, Cangxian County set up a transshipment ambassador to manage the saltworks, which was in charge of sea salt production in Hebei Province. In the Qing Dynasty, although this institution was moved to Tianjin, it was always called Luchang Salt Area. The beach here is wide and the bottom is covered with sediment, which is conducive to opening up salt fields; Windy and rainy, abundant sunshine and strong evaporation are conducive to seawater concentration; The salt people here are good at using favorable meteorological factors such as humidity, temperature and wind speed, and have rich experience in drying sea salt. These conditions provide a good foundation for the large-scale development of salt industry in this saltworks. The salt produced by Luchang Salt Field is famous at home and abroad for its large quantity, good quality, uniform particles and white color.
