The largest plain formed by the Yellow River is

Simply put, the North China Plain is the second largest plain in China. Located in the lower reaches of the Yellow River. It starts from Taihang Mountain and Western Henan Mountain in the west, reaches the Yellow Sea, Bohai Sea and Shandong Hill in the east, starts from Yanshan Mountain in the north, reaches Tongbai Mountain and Dabie Mountain in the southwest, reaches northern Jiangsu and Anhui in the southeast, and is connected with the plain in the middle and lower reaches of the Yangtze River. It extends to Beijing, Tianjin, Hebei, Shandong, Henan, Anhui and Jiangsu provinces. The area is about 3 1 10,000 square kilometers. The North China Plain has a warm temperate monsoon climate with obvious changes in four seasons. The Huaihe river basin in the south is in a transitional area to the subtropical zone, and the temperature and precipitation are higher than those in the north. The average annual temperature in the plain is 8 ~ 15℃, and it is cold and dry in winter. Most crops are harvested three times a year and twice a year in the south.

If you often watch the weather forecast, you will often mention the North China Plain, which is sometimes called the Huanghuai Plain according to the actual situation, but it should be called the Huanghuaihai Plain, which is mainly alluvial by the Yellow River, Huaihe River, Haihe River and Luanhe River, so it is also called the Huanghuaihai Plain.

According to the different regional characteristics of North China Plain, it can be divided into four sub-regional plains: the lower reaches of Liaohe River Plain, Haihe River Plain, Yellow River Plain and Huaibei Plain.
