在黄河上游自然地理条件下 ,黄河上游大洪水具有峰低、量大、持续时间长的特点 ,而宁蒙冰凌冰水每年都会有程度不同的灾害发生。在龙羊峡、刘家峡水库联合运用后 ,要发挥好工程措施和非工程措施的防洪作用 ,在防治黄河上游大洪水的同时更要重视冰凌洪水的防治。
In the natural environment of the upper reaches of the Yellow River, the floods in the upper reaches of the Yellow River have the characteristics of low peak, large amount and long duration, while ice, ice and water in Ningmeng County have varying degrees of disasters each year. After the combined use of Longyangxia and Liujiaxia Reservoirs, it is necessary to give full play to the flood prevention effects of engineering measures and non-engineering measures. At the same time, it is necessary to pay more attention to the prevention and control of ice floods while preventing the floods in the upper reaches of the Yellow River.
