The "Pearl of the Yellow River," Bayannur is a lush agricultural oasis on the great river's northern bend, famous for its sunflower fields, Hetao irrigation system, and primeval Yinshan rock art.
Bayannur, meaning "rich lake" in Mongolian, is a prefecture-level city in western Inner Mongolia, situated on the northern bank of the Yellow River's great bend — the Hetao region. This location has given it the nickname "Pearl of the Yellow River."
The Hetao plain is one of China's most important agricultural regions, made fertile by the Hetao Irrigation System — a network of canals that has been operating for over 2,000 years. The system diverts water from the Yellow River to irrigate the otherwise arid plain, enabling the cultivation of sunflowers, wheat, corn, melons, and other crops. Bayannur produces one-third of China's sunflower seeds and is famous for its sweet Hetao melons.
The Yinshan Mountains, running through the northern part of the city, contain an extraordinary gallery of ancient rock art. Over 15,000 petroglyphs carved into the dark volcanic cliffs depict the lives, beliefs, and environment of the nomadic peoples who have inhabited this region for millennia. These carvings represent one of the most significant rock art collections in China.
Ulan Suhai Lake, in the eastern part of Bayannur, is the largest wetland in the Yellow River basin. This vast lake and its surrounding marshes support an extraordinary diversity of birdlife and serve as a critical stopover point for migratory birds on the East Asian-Australasian Flyway.
The Hetao region has been inhabited for thousands of years. The Yinshan rock art, created over 10,000 years, documents the continuous presence of nomadic peoples. During the Qin and Han dynasties, Chinese empires expanded into the region, building defensive walls and the first irrigation canals.
The Hetao Irrigation System was first developed during the Western Han Dynasty (206 BC - 24 AD). General Zhao Chongguo initiated military agricultural colonies in the region, digging canals to water crops. This system was expanded and maintained by successive dynasties.
During the Mongol Empire, the region was part of the vast Mongol domains. In the Qing Dynasty, the area was organized under Mongol banner administration. Han Chinese farmers migrated to the Hetao plain during the late Qing and Republican periods, expanding agricultural settlement.
The modern city of Bayannur was established in 2004, upgrading from Bayannur League to prefecture-level city status. Today, it balances its agricultural heritage with ecological conservation, particularly the protection of Ulan Suhai Lake and the Yinshan rock art sites.
Bayannur's economy is dominated by agriculture and food processing. The Hetao irrigation system supports cultivation of sunflowers, wheat, corn, melons, and tomatoes. The city is China's largest sunflower seed producer, accounting for one-third of national output. Hetao melons are famous nationwide, and the region also produces high-quality wheat for noodles and bread.
Livestock farming, particularly sheep and cattle, is significant. The Yellow River fishery provides fish to local and regional markets. Food processing industries include oil pressing (sunflower oil), flour milling, and fruit and vegetable canning.
Tourism is a growing sector, focused on the Yinshan rock art, Ulan Suhai Lake wetland, and agricultural tourism such as sunflower field visits.
