摘　　要：本文根据青铜峡灌区四水转化的特点和灌区规划的要求 ,提出灌区节水改造规划的水土资源平衡应进行水资源的 3个平衡分析 ,即水资源供需平衡分析 ,引水、耗水与排水平衡分析 ,水资源耗水平衡分析 .水资源的 3个平衡分析的目标与内容不同 ,但科学基础与依据都是灌区的四水转化关系 .The balance of water resources in Qingtongxia Irrigation Area is studied. Based on the principle of transformation among surface water, soil water, ground water and water in atmosphere, the analysis on balance of water resources in three aspects is carried out for the water saving planning of the irrigation area. The aspects include the balance of water supply and demand, the balance of water delivery water consumption water drainage and the balance of water consumption.
