黄河下游河南、山东两省6县(市)堵复、新修生产堤的复清工作,在国家防总、水利部的直接领导、督促下,经过沿黄各级政府、河务部门及广大群众的共同努力,于7月16日完成。黄河下游滩区生产堤主要建于1958～1973年这段时间。生产堤修建后,尽管减少了洪水漫滩机遇,缩小了局部灾害,但就大局来讲,缩窄了行洪河道,降低了天然河道滞洪、削峰作用,加重了河槽淤积,河道横比降加大,形成了“槽高、滩低、堤根洼”的危险局面。鉴于这
In the lower reaches of the Yellow River, 6 counties (cities) in Henan and Shandong provinces blocked the resettlement work of the newly-built production dike. Under the direct leadership and supervision of the national defense and water resources ministry, after all levels of government and river affairs departments along the Yellow River and vast The joint efforts of the masses, completed on July 16. The beach area of the lower reaches of the Yellow River is mainly built in the period 1958 ~ 1973. After the completion of the production dike, despite the reduction of flooding floodplain opportunities and the reduction of local disasters, in general terms, it narrows the flood-releasing channels and reduces the detention and clipping effect of natural channels, aggravating the sedimentation of river channels, Increase, forming a “trough height, beach low, embankment depression ” dangerous situation. In view of this
