摘　　要：利用环境减实卫星遥感监测影像,分析了2010年黄河调水调沙下游河势现状,并通过对比近几年河势变化情况,分析了调水调沙对河势的影响。结果表明:①经过多年调水调沙,黄河下游河道主槽刷深,过流能力大大增强,河势也相对稳定;②一些原来靠溜较好的工程,如驾部、南裹头、马庄、马渡险工等,有脱河脱溜的趋势,建议对这些河段加强河势变化监测;③在多年调水调沙作用下,毛庵—三官庙、黑岗口—东坝头河段工程靠溜状况趋好,河势逐步向有利方向发展,尤其是柳园口—欧坦工程河段,大部分原来不靠河的工程开始逐步靠溜,当前河势较为顺畅。The paper analyzes the present status of the lower Yellow River regime after the regulated discharge regime conducted in 2010 by using remote sensing images of environmental satellite and analyzes the influence of regulated discharge regime to the river regime through the variation comparison of river regime in the last few years.The outcomes show that a) the main channel of the lower Yellow River has become deeper,loading capacity greatly increased and river regime also relatively stable after several years' regulated discharge regime of the river;b) the vulnerable spots of Jiabu,Nanguotou,Mazhuang and Madu where main current used to be contacted with has the trend of off the main current.It suggests to monitor the variation of river regime of those sections and;c) the engineering works at the sections of Maoan-Sanguanmiao and Heiguangkou-Dongbatou has a better trend of contacting with the main current,the river regime develops gradually to a positive direction,especially the majority engineering works at Liuyuankou – Outan section is gradually contacting with the main current where used to be off the flow and the present river regime is fairly smooth.
