CCTV News: On October 14, at the 77th International Executive Council Meeting of the International Commission on Irrigation and Drainage held in Marseille, France, the 2026 World Irrigation Engineering Heritage List was officially announced, and all four irrigation projects submitted by my country were successfully selected.So far, China's total number of world irrigation engineering heritages has reached 46.
There are 4 irrigation projects applied for in our country this time, namely the Guangli Canal of Qinhe River in Henan, the Oasis Irrigation System of Tuolai River in Gansu, the Guangxin Huangsha Canal in Shangrao City, Jiangxi, and the Gubei Irrigation Project of Changtai Longjin in Fujian.
The Qinhe Guangli Canal is located in the northwest of Henan Province. It was first built in the Qin Dynasty and has a history of more than 2,200 years. It adopts a multi-canal headless water diversion irrigation model. It is one of the few large-scale irrigation areas in China that completely retains the main irrigation water diversion engineering structure of the Ming Dynasty. It irrigates 510,000 acres of fertile farmland in Jiyuan and Jiaozuo, making it the main grain production core area in Henan Province.
The Tuolai River Oasis Irrigation System is located in the middle of the Hexi Corridor. It was built in the Ming Dynasty. It consists of three core parts: the flood river Dongzi Canal, the Tuolai River Mainstream Canal System, and the Linshui River-Qingshui River Canal System. The total irrigated area is 947,800 acres. It is a typical representative of the oasis irrigation system in the arid areas of the Eurasian continent.
Guangxin Huangsha Canal is located in Shangrao City, Jiangxi Province. It was built in the Song Dynasty and is a model of low-impact development of small watersheds in ancient mountainous areas in my country.Using distributed cascade development, canals and ponds are built from lowlands to highlands and from bottom to top, forming a gravity irrigation engineering system that irrigates more than 10,000 acres of farmland and nearly 10,000 acres of forestland.
Changtai Longjin Gupi Irrigation Project is located in Changtai District, Zhangzhou, Fujian Province. It was built in the Song Dynasty and has a history of more than 800 years. It is a typical model of "low dam + long vines and melons" on mountainous rivers along the southeast coast. The existing irrigation area is 27,700 acres.
