摘　　要：龙羊峡、刘家峡水库投入运行以后,黄河内蒙古河段的防凌防洪形势依然非常严重,凌洪灾害时有发生。分析其原因,除了内蒙古河段自身的地理条件和气候因素外,水沙关系严重失调,水流输沙能力下降,主河槽持续淤积,过流能力降低也是重要原因。本文从分析龙羊峡、刘家峡水库运行前后内蒙古河段的凌汛特点、水沙条件变化规律入手,比较全面地分析了黄河内蒙古河段的防凌需求和防洪需求,并初步提出了内蒙古河段的防凌防洪总库容。There is still a pressing situation of ice-flood control and flood control in Inner-Mongolia reach of the Yellow River af- ter the reservoirs of Longyangxia and Liujiaxia have been operated, with ice-flood disasters frequently occurs. Analyzing the reasons, the imbalance relationship between water and sediment, sediment transporting capacity reduction, continuous sedimentation in the main channel, and discharge capacity decreasing are important causes in addition to the geographical and climatic factors in the Inner-Mongolia reach. This paper studied the ice-flood characteristics and the change of relationship between water and sediment before and after building the reservoirs of Longyangxia and Liujiaxia, analyzed ice-flood control and flood control demand in the Inner-Mongolia reach of the Yellow River, and calculated the total reservoir volume concerning with the ice-flood control and flood control in the Inner-Mongolia reach.
