Abstract: Dong Ying City located in the Yellow River mouth is the locus of the second biggest oil field in China£­Shengli oilfield. Because the problem of the Yellow River mouth¡¯s zero-flow has been gradually serious since the early 1970's, large amounts of reservoirs storing and adjusting water has been built in river mouth area as far back as mid 1980¡¯s in order to resolve its zero-flow and ensure the development and resources exploitation of the city and the oilfield. Only the oilfield has 17 reservoirs whose design capacity is 376 million cubic meters. In order to manage and allocate the Yellow River water resource rationally and effectively, the Yellow River Estuary Bureau takes full advantage of these reservoirs in river mouth and has carried out the innovations about the sluices control and application methods and water supply managing mechanism, while splitting water supply in alternate time according to two different characters of the water utilization£­agricultural water and non-agricultural water, which is called¡° the separate water supply¡±. This method has fundamentally dissolved the water contradiction of competing for water between agriculture and industry and has built new harmonious high-effect local water utilization order, has made sufficient utilization of limited water resources and has had adjusted the Yellow River water supply structure effectively and has got good economic and social benefits.
