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

    • 摘要: 黄河上游灌区长期以来过量引水,不仅造成土壤次生盐碱化,而且成为黄河每年多次断流的一个重要原因。引入农业用水量、水盐平衡等新概念,结合典型灌区,进行全区域灌溉制度设计方法探讨,其成果可用于井渠结合类型灌区设计及旧灌区改造。

       

      Abstract: 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.
