采用实测资料分析和理论探讨的方法,研究了引黄灌区渠道淤积的负面影响。研究结果表明:引黄灌区渠道淤积加大了渠道清淤难度,加重了排水河道负担,同时清淤堆沙占压了大量耕地,破坏了生态环境;引黄灌区渠道自身几何要素包括比降、断面形态等不合理是造成渠道淤积的根本原因,引水引沙管理不善也是加重渠道淤积的原因之一。 Using the measured data analysis and theoretical methods, the negative effects of channel deposition in the Yellow River Diversion Irrigation District were studied. The results show that the channel siltation in the Yellow River Irrigation District increases the difficulty of channel dredging and aggravates the burden on the drainage channel. At the same time, the dredging and sand dredging occupy a large amount of cultivated land, destroying the ecological environment; The irrational cross-section morphology is the root cause of channel siltation, and the poor management of diversion and sediment introduction is also one of the reasons for aggravating the channel siltation.
