The sources of salt in China are divided into three categories: well salt, sea salt and lake salt, of which well salt accounts for 87%, sea salt accounts for 10% and lake salt accounts for 3%. Judging from the consumption structure of China, well salt and lake salt account for 90%, both of which have nothing to do with nuclear pollution and are safe.

The main salt producing areas in China are widely distributed, from the northeast to Hainan and Taiwan Province provinces, and from Xinjiang, Qinghai, Sichuan and Tibet to Inner Mongolia. There are many kinds of salt produced: sea salt, well salt, rock salt and pond salt. Among them, the salt fields in Liaoning, Shandong, Huaibei and Luchang are rich in sea salt, which has been famous since ancient times.

Well salt is the most famous artesian well in Zigong City, Sichuan Province, with a history of 1000 years. Rock salt is produced in Sichuan, Yunnan, Hubei, Hunan, Xinjiang, Qinghai and other places. There are many salt lakes in Shaanxi, Shanxi, Gansu, Qinghai, Xinjiang, Inner Mongolia, Heilongjiang and other places, and the pool salt is rich, the largest of which is Chaerhan Salt Pool in Qaidam Basin. According to statistics, the pool salt mined by this salt pond alone is enough for China/Kloc-0.2 billion people to eat for more than 4,000 years.

Salt production in China:

1. The total annual salt consumption in China is basically stable at 7 million tons (this amount is directly proportional to the population, and there will be no big fluctuations as long as the population does not change greatly), while the annual salt output in China exceeds 40 million tons, most of which are used as chemical raw materials. These abilities can easily produce enough salt once needed.

2. In the national salt, the proportion of sea salt is decreasing year by year, and people usually eat mostly well salt. The main reasons are as follows: first, there are many impurities in sea salt, and the purification cost is high and uneconomical; Second, the sea salt field occupies too much land, and the coastal beaches are very valuable. They gradually turned to seafood farming and land development, and the profit rate of salt production was too low. In fact, in the economically developed southern region, the sea salt field has long declined, which is purely due to economic laws.

3. Well salt and mineral salt are very abundant. Just one salt mine has hundreds of millions of tons of reserves. It is not a problem for the people of the whole country to eat for hundreds of years, and it is also widely distributed. Sichuan, Hubei, Hunan, Shaanxi, Jiangsu, Henan, Jiangxi and Qinghai are all big producing areas, so transportation is not a problem.

4. China's salt circulation is a state monopoly, and the price is strictly controlled. There is no need to worry about the price increase. Even if it is temporarily sold out, the supply capacity of salt companies around the country will soon ensure supply. Although the franchise system has various disadvantages, it still has advantages in ensuring the supply of salt.
