On the morning of October 6th, Beijing time, at the 24th International Congress on Irrigation and Drainage & 73rd IEC Meeting held in Adelaide, Australia, the List of Heritage Irrigation Structures in 2022 (the ninth batch) was released. Four projects, Tongjiyan in Sichuan Province, Stack Field in Xinghua in Jiangsu Province, Songgu Irrigation District in Songyang, Zhejiang Province, and Shangbao Terrace in Chongyi, Jiangxi Province, have all been successfully declared.

Stack field, known in ancient times as Fengtian and Jiatian, also known as Changan, Dao, Tuo, etc., is a unique artificial landform formed by the ancestors of Xinghua in order to resist frequent floods and floods, accumulating soil into mounds, building soil into mounds, taking mounds as fields, and planting them. This is the crystallization and model of people using nature, transforming nature and living in harmony with nature. It is also a masterpiece of farmland flood control and disaster avoidance in Lixiahe area, which shows the wisdom and spirit of perseverance of Xinghua ancestors to survive and continue the future generations.

Xinghua stack field irrigation and drainage engineering system is unique in the hinterland of Lixiahe River in Jiangsu Province, and the only irrigation and drainage engineering system in upland dry land at home and abroad.

Xinghua stack field irrigation and drainage engineering system has a total irrigation area of 52.88 square kilometers, which is distributed in Xinghua Lake Dang area. It is a composite irrigation and drainage engineering system with supporting dikes, irrigation and drainage channels and sluices. “It has an important position and unique representation in the history of irrigation and drainage engineering, and has a high historical, scientific and cultural value.” According to the relevant person in charge of the Ministry of Water Resources, Xinghua stack field irrigation and drainage engineering system is a creative engineering system between Yangze river and Huai river and coastal plain, which is different from polder fields and embankments in other water network areas. It reflects the will of national flood management under the premise of coordinating the relationship between the Yellow River, Huaihe River and canal, and is still exerting various benefits such as irrigation and drainage, flood control and drought relief, ecological agriculture and landscape tourism. The traditional farming methods of farmland water conservancy, such as placing, hoeing, bailing, taking mud from the bottom of the river for fertilizer, stripping tool and pressing aquatic plants, have been kept and still used today.
