摘要

The Lower Yellow River irrigation areas is one of the three biggest regional irrigation areas of Yellow River Basin, belonging to irrigation-supplement zone, which has three sources of irrigation water, including the water diverted from Yellow River, the ground water and the local surface water. It is calculated that average water consumption is 14 billion m3, among which Yellow River water is 8.84 billion m3, ground water is 4.37 billion m3, surface water is 0.82 billion m3, and the respective proportion is 63%, 31%, and 6%. The total water consumption of lower Yellow River irrigation area descends gradually year by year, in which Yellow River water and surface water decrease and ground water increase slowly.
