宁夏灌区续建配套与节水改造项目良田渠治理措施

Control Measures of Liangtian Canal of Rehabilitation Matching and Water Saving Reform Project in Ningxia Irrigation Area

宁夏引黄灌区历史悠久,是我国大型灌区之一。自实施宁夏引黄灌区续建配套与节水改造项目以来,灌区骨干工程安全状况有了较大改善,渠道综合调控能力不断增强,灌区节水意识进一步提高。良田渠灌域是青铜峡河西灌区的组成部分,通过渠道砌护及建筑物新建、维修等改造工程措施,提高灌溉水利用系数,减少引黄水量,完善渠道防洪体系,为渠道提供安全的行水条件。对灌区经济持续发展和工程效益的充分发挥起到推动作用,同时对改善渠道沿线生态环境和城市美化也具有积极意义。

Irrigated areas by Yellow river of Ningxia has a long history, and it was one of the large irrigation areas in China. Since implementation of rehabilitation matching and water saving reform project in irrigated areas by Yellow river of Ningxia, safety situation of backbone project in irrigation district has been greatly improved, channel comprehensive regulation and control ability has been constantly enhanced, water saving consciousness of irrigated area has been further increased. Liangtian canal ir- rigated area was a component of west irrigated area of Qingtong gorge. Through transformation engineering measures including channel lining, newly building and repair of structure, irrigation water use coefficient was improved, water from Yellow river was reduced. Channel flood control system was improved. It provided safe water conditions for channel. Implementation of this project played role in promoting economy continues to grow and engineering benefits full playing in irrigated areas. And at the same time, it also had positive significance to improve ecological environment and urban beautification along the channel.
