黄河下游沿黄地区地下水质较好,开采地下水较开采地表水流量稳定,可节省泥沙处理费用。为此,作者提出应尽量开采地下水源。并建议在古河道主流相沉积地区,井离大堤要超过抽水影响半径2～3倍,井排方向以沿大堤走向为好,排距400m、列距500m,井径0.6～0.9m,成井深度一般为80m。 The groundwater quality along the Yellow River in the lower Yellow River is good, and the exploitation of groundwater is more stable than the exploitation of surface water, which can save sediment disposal costs. To this end, the author proposes that groundwater sources should be exploited as much as possible. It is also suggested that in the main sedimentary area of ​​the ancient channel, the well should exceed the dike by more than 2 ~ 3 times the radius of the affected area. The direction of well row should be along the dike, with a row spacing of 400m, a row spacing of 500m and a well diameter of 0.6 ~ 0.9m. Generally 80m.
