黄河水少沙多是下游河道强烈堆积的原因,河道逐年淤积抬高,给下游防洪带来严重威胁。为了研究减缓下游河道淤积,黄委会曾会同清华大学、武汉水利学院等单位分别对黄河中下游大面积放淤减沙方案规划进行过初步研究。总的设想是利用大面积滩区和低洼盐碱下湿地进行放淤改土,减少来沙,达到减缓下游河道淤积和改善农业生产的目的。
The Yellow River water and sand less than the strong accumulation of the lower reaches of the river, siltation uplift year by year, to the downstream floods pose a serious threat. In order to study the mitigation of siltation in the lower reaches of the river, the Yellow River Council conducted a preliminary study on plans for large-scale siltation and sediment reduction in the middle and lower reaches of the Yellow River with units such as Tsinghua University and Wuhan University of Water Resources. The general idea is to make use of the large area beach area and the low-lying saline-alkali wetland for siltation and soil modification to reduce the incoming and outgoing sediment, so as to reduce the siltation of downstream rivers and improve the agricultural production.
