黄河上游干流水库对内蒙古河段的影响

利用常规资料与多时相卫星遥感图像，分析了黄河上游干流水库投入运用后内蒙古河段河床的冲淤演变及平面形态变化。结果表明：刘家峡水库建成后，内蒙段河道轻度冲刷，河床摆不显著，龙羊峡水库运用初期，内蒙河段水沙变化较大，河床淤积，平面摆动剧。防震预计龙羊峡水库正式运用后，龙、刘两库联合调度，内蒙河段有淤积趋势，河床摆状态不会有明显改变。

Influence of Reserviors in Main Streem or the Upper Yellow River on the Reach Within Inner Mongolia Autonomous Region

Using routine information and multitime phase satellite remote sensing images, the paper analysed the scour and silting evolution and plane form variation of river bed in Inner Mongolia reach after the reserviors in main streem of the upper Yellow River were put to use. After the Liujiaxia Reservior was set up,the channel in inner Mongolia region was washed slightly and river bed swing was not obvious; in the initial utilization stage of Longyangxia Reservior,the water flow and sediment content in the reach varied greatly, the river bed silted and swang severely.After Longyangxia Reservior is put to normal use, with the combined regulation 'Of the two reserviors, the river bed in the reach will have the trend of siltation,the swing status of river bed will not change obviously. Therefore, the paper proposed prevention measures such as building self-regulation reservior in Haibowan.
