The largest saltworks and fishing grounds in China are

The largest salt fields and fishing grounds in China are Luchang Salt Field and Zhoushan Fishing Ground.

Luchang Yanchang

Yantian, with the largest sea salt production in China, accounts for a quarter of the total sea salt production in China.

Cangzhou, Hebei Province, in particular, is the largest producer of industrial salt in China, and the daily output of industrial salt is the most important salt field in China compared with the annual output of medical salt in Taiwan Province Province. Because there is no technology to produce medical salt for the time being, especially the third and fourth generation medical salt, which is the largest in the mainland and the second in the country.

Distribution position

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 and sun-dried salt: 1. There are long, wide and flat muddy beaches. The weather is favorable for seawater evaporation, which is a short rainy season. In spring, the temperature rises rapidly and evaporates vigorously.

terrain condition

Flat terrain and wide beaches; It is 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.

Zhoushan fishing ground

Located in the northeast of Zhejiang, east of Hangzhou Bay and southeast of the Yangtze River estuary, it covers an area of about 53,000 square kilometers with latitude 29 30 ′ ~ 365 438+0 00 ′ and longitude 65 438+020 30 ′ ~ 65 438+025 00 ′. It is the largest fishing ground in China and a traditional fishing area for fishermen in Zhejiang, Jiangsu, Fujian, Shanghai and Taiwan Province provinces. The four major economic fish are Pseudosciaena crocea, Pseudosciaena crocea, hairtail and cuttlefish. Due to long-term fishing and marine pollution, fishery resources have been seriously damaged.

geographical position

Zhoushan fishing ground is located in the north of the East China Sea, near the east coast of the mainland and southeast of the Yangtze River estuary, outside the Qiantang River estuary and south of the Yangtze River estuary fishing ground, with an area of about 14350 square nautical mile, with a latitude of 29 30 ~ 365 438+000 ˊ and an longitude of 65 438+02500 ˊ.

Zhoushan Fishing Ground is located in the east of Zhouwai Fishing Ground, connected to Yushan Fishing Ground in the south and the Yangtze River Estuary Fishing Ground in the north, covering an area of about 53,000 square kilometers. The seabed is mainly composed of fine-grained sedimentary mixtures such as silty ooze and clayey ooze, which is an integral part of the continental shelf of the East China Sea. The water depth is generally 20 ~ 40 meters. The north-south 80-meter isobath is 280 ~150km wide from the shore.
