淤地坝是黄土丘陵沟壑区治沟工程的一项重要措施。建国三十多年来,我县已建成淤地面积10亩以上的淤地坝1984座,已淤坝地4.82万亩,利用3万亩,每年产粮约7500吨,占全县粮食总产的11.8％,拦蓄泥沙9000万立方米,为减少入黄泥沙,发展农业生产发挥了巨大的作用。这些淤地坝大都建于60年代末期和70年代,未经统一勘查、规划,多为群众自发搞起来的,只能抵御5～10年一遇的洪水,防洪标准较低,现在多数坝已基本淤满,处于危险状态。因此,通过全面规划,对已建淤地坝有选择、有计划地进行加高改建,提高防洪标准,防止暴雨情况下的水毁,以充分发挥水保效益和生产效益,已成为群众的迫切要求。这也是当前水利水保战线一项刻不容缓的重要任务。 Warping dams are important measures for trench management in loess hilly and gully regions. Over the past 30 years since the founding of the People’s Republic of China, 1984 has completed the construction of 1984 silt dam with a silt land area of ​​more than 10 mu, and has used 48,200 mu silt dam and utilized 30,000 mu to produce about 7,500 tons of grain per year, Of the 11.8%, silt sediment 90 million cubic meters, to reduce the Yellow River sediment, agricultural development has played a huge role. Most of these silt dams are built in the late 1960s and 1970s. Without unified surveys and planning, they are mostly built spontaneously by the masses and can only withstand flooding once in 5 to 10 years with low flood control standards. Basic silt, in a dangerous state. Therefore, through comprehensive planning, it has become urgent for the masses to urgently choose to rebuild the silt dam that has been constructed, increase and rehabilitate it in a planned way, raise flood control standards and prevent water damage under heavy rainfall so as to give full play to benefits of water conservation and production Claim. This is also an urgent important task for the current water conservancy and hydropower.
