黄河调水调沙已有14余年,黄河河势变化较大,河床拉深下降,扩大了过水断面,有利于黄河行洪,为确保黄河安澜起到了重要作用。但随之而来的负面影响,给沿黄农田灌溉带来了困难,沿黄各地都在探讨消除黄河调水调沙带来的影响。文章结合范县于庄引黄灌区节水配套改造工程,探讨了如何消除因黄河调水调沙带来的负面影响。
The Yellow River has more than 14 years of water and sediment regulation. The Yellow River has great changes in river potential, and the riverbed has been deepened and lowered, expanding the cross-section of the Yellow River and facilitating flood discharge of the Yellow River, playing an important role in ensuring the tranquility of the Yellow River. However, the ensuing negative impacts have caused difficulties in irrigating farmland along the Yellow River. The impact of water and sediment adjustment on the Yellow River has been discussed in various parts of the Yellow River. This article discusses how to eliminate the negative influence brought by the water and sediment adjustment of the Yellow River in connection with the water-saving ancillary renovation project in Fanxian Yellow River Irrigation Area.
