1 鸭河口灌区节水灌溉成效鸭河口灌区“九五”期间,国家、省、地方财政及群众自筹共投入灌区节水改造、节水灌溉资金1.28亿元,发展节水灌溉工程面积4.13万hm~2,低压管道输水灌溉面积0.13万hm~2;水稻节水灌溉等非工程节水面积近2万hm~2,新增粮食生产能力3012万kg,农民水费负担明显减轻。1.1 提高了工程输水能力。通过灌区节水改造,局部险工险段和滑坡阻水问题得到了根本解决。骨干工程输水能力提高了13%。特别是白桐干渠部分渠段衬砌后效果尤为明显。经放水测算,输水能力由改造前的75m~3/s提高到了110m~3/s。社旗分
1 duck water estuary irrigation water-saving irrigation effect duck mouth estuary irrigation During the “nine five ” period, the state, province and local finance and the masses raised a total investment in water saving irrigation area, water-saving irrigation funds 128000000 yuan, the development of water-saving irrigation project area 41000 hm ~ 2, and the low-pressure pipe irrigation area is 130000 hm ~ 2. The non-engineering water saving area such as rice water saving irrigation is nearly 20,000 hm ~ 2, the new grain production capacity is 30,122,000 kg, and the peasant water fee burden is obviously reduced . 1.1 to improve the project water delivery capacity. Through water-saving irrigation area, partial risk insurance and landslide water blocking problem has been fundamentally resolved. Water transmission capacity of key projects increased by 13%. In particular, part of Bai Tong Drainage Canal lining effect is particularly evident. According to the calculation of water release, the capacity of water transfer is increased from 75m ~ 3 / s before the transformation to 110m ~ 3 / s. Social flag points
