灌区量水是实行计划用水,按方计征水费,促进节约用水和提高灌区管理水平的一项必不可少的重要工作;是合理调度灌溉水资源,正确执行用水计划,加强经济管理的必要措施;同时也是衡量灌溉管理水平和灌溉水利用率高低的重要技术手段。人民胜利渠灌区大多是利用建筑物量水,灌区兼作量水用的水工建筑物主要有水闸、涵洞、渡槽、陡坡、跌水等。通过灌区量水,可积累不同地区、不同水文年的农作物灌溉用水资料,分析核算灌区灌溉水的利用效率,检验原有农业用水定额的合理性。
The amount of water in irrigation districts is an essential and important task in implementing planned water use, collecting water fees on a per-square basis, promoting water conservation and improving the management level of irrigated areas; it is necessary to rationally schedule irrigation water resources, properly implement water use plans and strengthen economic management Measures; but also measure the level of irrigation management and irrigation water utilization rate of important technical means. People’s Victory Canal irrigation areas mostly use the amount of water in the building. The hydraulic structures that serve as water for irrigation are mainly sluices, culverts, aqueducts, steep slopes, and falls. Through the irrigation water, it is possible to accumulate crop irrigation water information in different regions and different hydrological years, analyze and calculate the irrigation water use efficiency, and test the rationality of the original agricultural water quota.
