Abstract: In recent years, due to the shortage of water resources and the increasing demand for water with the rapid socio-economic development and population growth, the contradiction between supply and demand for water resources is increasing in the Yellow River. Because of the serious deposition of the channel, the supporting projects of disrepair, the low utilization rate of water channels, the imperfect irrigation management and the decline of the supply guaranteed rate, the irrigated area is decreasing. Aimed at the contradiction between supply and demand of water resources, it need to combine the irrigation actual needs, to restore the expansion of the irrigation district through engineering and non-engineering measures, to establish a complete management and control means, to allocate the water resources rationally, and to transfer water scientifically, so that the limited water resources yield the greatest economic returns.
