In recent years， water and sediment regulation of the Yellow River changes the diversion conditions of Xiaokaihe Irrigation Area， which makes the irrigation area’s water supply and ecological security threatened. Aiming at the problem that is the decrease indiverted water volume of the Yellow River， serious deposit， no place for desilting spoil and the function shortage of desilting basin， etc. The reconstruction canal head project and construction of sand transmission pipeline and other engineering schemes are put forward. In order to implement ecological protection and high-quality development in the Yellow River Basin， a series of operations and management measures have been proved to be effective including using sediment resources， dispersing sediment， improved land， and heavier regulation. In the practice and exploration of dealing with the increasingly prominent contradiction between supply and demand of water resources and curbing the degradation of ecological environment in Xiaokaihe Irrigation Area， some accumulated practices can provide reference for the irrigation area of the lower Yellow River.
