引黄灌区干渠水量调度对管理节水成效的影响

Influence of Water Regulation in Main Canal of Yellow River Diversion Irrigation District on Management Water-saving Effect

从夹马口灌区的实际出发,结合管理节水的内涵,提出干渠水量调度与管理节水成效之间的关系及面临的问题。从渠道库容调蓄和渠道水头控制两个关键环节,论述了干渠水量调度的要求。通过夹马口灌区干渠适时利用率和《干渠水量调度规程》先后两次管理创新,比较了管理节水成效的提升,得出了推广《干渠水量调度规程》、按要求安装使用自动化计量器具和将适应黄河水的计量器具自动化、信息化、系统化等提高管理节水成效的结论。

Based on the practice of Jiamakou Irrigation District and the connotation of management water-saving,this paper puts forward the relationship between water regulation in main canal and management water-saving effect and the problems it faces. The requirements of water regulation in the main canal were discussed from the two key links of canal storage capacity regulation and canal water head control. The improvement of management water-saving effect was compared by timely utilization rate of the main canal in Jiamakou Irrigation District and Regulation on Water Regulation in Main Canals. The conclusion is that the promotion of Regulation on Water Regulation in Main Canals,the installation and use of automatic measuring instruments as required,and the automation,informatization and systematization of measuring instruments applicable to the Yellow River water can improve the effect of management water-saving.
