Design Method of Irrigation System for Water Saving and Salt Prevention in Irrigation Area

The excess water diversion in the irrigation area that locates in the upstream of Yellow River not only makes the secondary salinization of soil ,but also is one of the important reasons that cause the water interception repeatedly in Yellow River every year. The new conceptions of “the quatity of agriculture water use” and “balance of water and salt” are introduced in this paper. Based on these principles, irrigation regulation is designed for all regions. The result can be used to design well canal irrigation area and to transform the old irrigation area. At last, this paper discusses the importance of spreading new design method and the measures of realization on upper reaches of the Yellow River.
