为加速黄河中游多沙粗沙区治理,国家计委和水利部在“七五”计划期间,安排了水土保持治沟骨干工程试点工作。试点期内共新建和加固了249座大中型拦洪淤地坝,总控制流域面积2152.7km~2,总库容3.3亿m~3,其中拦泥库容2.1亿m~3,总造价4103.3万元其中国家投资补助2643.7万元,平均每座新建工程国家投资12.41万元,每m~3拦泥库容投资0.18万元。已通过竣工验收的工程中达质量优良者占89％。这些骨干工程已在缓洪拦沙淤地、灌溉、养鱼和改善当地生产条件等方面发挥了经济效益和社会效益。试点工作为今后大规模地开展水土保持治沟骨干工程建设,提供了组织管理和技术经验。
In order to speed up the management of the coarse and coarse sand area in the middle reaches of the Yellow River, the State Development Planning Commission and the Ministry of Water Resources have arranged the pilot projects of water and soil conservation and harnessing of key projects during the “7th Five-Year Plan”. During the pilot period, a total of 249 large and medium-sized flood control dam have been newly built and strengthened. The total control basin covers an area of 2152.7km 2 with a total storage capacity of 330 million m 3, of which 210 million m 3 are suspended sediment storage and the total cost is 410.33 million yuan Of this total, 26.437 million yuan was subsidized by the state, with an average investment of 124.1 thousand yuan for each new construction project and an investment of 18.8 yuan per m3 of mud storage capacity. Up to 89% of the projects that have passed the final inspection and acceptance are of good quality. These key projects have exerted economic and social benefits in such areas as slowing floods and stopping silting, irrigating, raising fish and improving local production conditions. Pilot projects for large-scale soil and water conservation in the future to carry out the construction of the backbone project, provided organizational management and technical experience.
