摘　　要：宁夏银北灌区开发利用地下水资源,井灌井排,能有效降低地下水位,防止土壤次生盐碱化,其次,开发利用地下水资源,井渠互补,使农作物得到适时灌溉,同时也是发展喷灌、滴灌等节水技术的理想水源,就银北灌区井灌规划和井泵优化配套提出了计算方法。The groundwater resources were developed and utilized in irrigated area in North of Yinchuan, Ningxia. The well irrigation and well drainage can reduce water level effectively and prevent soil from the secondary salinization. Combination of the well and canal can make the crops irrigate in good time. It is ideal water source to water-saving technology, such as sprinkling irrigation and dripping irrigation etc. at the same time. This paper has put forward a calculating method for the well irrigation planning and optimization in irrigation district in North of Yinchuan, Ningxia.
