摘　　要：农业是永定河流域用水大户,农业用水占到了永定河流域总用水量的70%以上,实施农业节水是保障永定河生态水量的重要措施。对七一灌区水量进行供需平衡分析计算,根据水量供需缺口,从工程与管理方面提出相应的节水措施,达到《永定河流域农业节水工程实施推进方案》提出的节水目标。Agriculture is a major water user in Yongding River basin,accounting for more than 70%of the total water consumption in Yongding River basin.Implementing agricultural water-saving is an important measure to guarantee the ecological water quantity in Yongding River Basin.This paper analyzes and calculates the balance between water supply and demand in the irrigated area,and puts forward corresponding water-saving measures from the aspects of engineering and management according to the gap between water supply and demand,so as to achieve the water-saving target proposed in the Implementation and Promotion Plan of Agricultural Water-saving Project in Yongding River Basin.
