人民胜利渠是建国初期在黄河下游兴建的第一个大型引黄灌溉工程,自1952年开灌以来,已经运行38年。随着时间的推移,灌区工程老化、年久失修的现象日益严重,而且灌溉水的有效利用率始终徘徊在0.4左右,土壤次生盐碱化的问题亦令人担忧。为了使老灌区获得新生,人民胜利渠作为技术改造试验区先后被列入国家“六五”、“七五”科技攻关项目,目前已完成支渠以下改造面积7.7万亩,取得了显著的经济效益。
The People’s Victory Canal was the first large-scale project to divert water from the Yellow River to the Yellow River during the early days of the founding of the People’s Republic of China. It has operated for 38 years since it was started in 1952. With the passage of time, the phenomenon of aging and long-term disrepair of irrigation districts has become increasingly serious. The effective utilization rate of irrigation water has been hovering at around 0.4. The problem of secondary salinization of soils is also worrying. In order to rejuvenate the old irrigated area, the People’s Victory Canal, as a pilot area for technical renovation, has been listed in the national “Sixth Five-Year Plan” and “Seventh Five-Year Plan” scientific and technological project. At present, the area for reconstruction below the branch canal has been completed to be 77,000 mu with remarkable economic benefits .
