Jiangnan plain

The Jiangnan plain, also known as the Yangtze Plain, is a series of alluvial plains in east-central China, situated along the Yangtze River and its tributaries. This fertile region is characterized by low-lying, level land, with most areas below 150 feet (45 meters) above sea level. It is a densely populated and highly industrialized area, known for its rich agricultural output, including rice, cotton, and silk.123

The Jiangnan region is divided by the Yangtze River estuary into two sections: Jiangnan (south of the river) and Subei (north of the river). Jiangnan is particularly fertile, well-watered, and famous for its silk and handicrafts. Major cities like Shanghai, Nanjing, Suzhou, and Wuhan are located here. The area is crisscrossed by a network of navigable waterways, and flood control projects have been implemented to manage the rivers.31
