河南省偃师县伊东渠自伊河引水,是兴建于清道光年间的老灌区,经1959—1962年扩建,灌溉面积达8万亩。1984年以来,改“以亩计收”为“按量收费”,建立了专管和群管分水配水队伍,实行了包灌溉面积、包灌溉水量、包水费计收的“三包”责任制,促进了工程的维修、养护,形成了良好的灌溉秩序,工程效益明显提高。水费制度实行“三包”后,灌溉周期由25天减少到18天;亩次平均耗水由125立方米降低到98立方米。1985年,全灌区普浇5遍水,超
The Yudong River in Yanshi County, Henan Province leads the water from the Yi River and is an old irrigation area built during the Qing dynasty. With an expansion of 1959-1962, the irrigation area reached 80,000 mu. Since 1984, we have changed “take charge of mu” as “charge by volume” and set up special teams for water management and water management. We implemented the “Three Guarantees” package of irrigation area, irrigation water and water charges, The responsibility system promoted the maintenance and conservation of the project and formed a good irrigation order with a marked improvement in project benefits. After the implementation of the Three Guarantees system, the irrigation cycle was reduced from 25 days to 18 days. The average water consumption per acre was reduced from 125 cubic meters to 98 cubic meters. In 1985, the whole irrigation area poplar 5 times water, super
