Water diversion to large irrigation districts constitutes most of the water resources extracted from China's Yellow River. The Hetao irrigation district in Ningxia and Inner Mongolia takes 40% of the water from the Yellow River, and has many problems such as water over-consumption, low irrigation efficiency and soil salinity. The Yichang irrigation sub-district was used as an example to study the water and salt balance. Examination of water use and water balance data shows that soil salinity is a problem, and emphasises the importance of internal drainage and dry drainage.
