Is the ancient irrigation area of Ningxia Yellow River Diversion Project included in the World Heritage List of Irrigation Projects?
Ningxia ancient irrigation area is located in the ancient irrigation area of Yellow River Diversion in Ningxia Hui Autonomous Region, which was built in Yuanshou period of Western Han Dynasty (BC 122 ~ BC 1 17). At that time, this area was recovered from the Xiongnu rule and was reclaimed on a large scale.
The ancient irrigation area of Yellow River Diversion in Ningxia Plain has been reclaimed and developed since Qin Dynasty, with a history of more than 2,000 years. At present, it has an irrigation area of 8.28 million mu, which is one of the oldest and largest irrigation areas in China. It experienced the development of immigrants in the Han Dynasty, the construction of dikes and water diversion in the Tang Dynasty, the construction of dams and weirs in the Yuan Dynasty, the dredging and renovation in the Ming Dynasty, and the integration of land and water in the Qing Dynasty. A criss-crossing and closely woven irrigation ancient canal system covering Ningxia Plain has been gradually formed, creating a rich and splendid "frontier fortress south of the Yangtze River", which has promoted the transformation of Ningxia Plain from nomadic civilization to farming civilization and the integration and development of different cultures. It has long been the foundation of regional socio-economic development and oasis ecological environment stability, and has important strategic significance for the political and economic stability of northwest China.
