【 摘 要 】

The provincial hydrological sections of Shizuishan and Toudaoguai are selected as the object of study to analyze flow process variation degree and influencing factor in Inner Mongolia reach of the Yellow River, according to observe and natural monthly runoff from 1956 to 2013. The result shows that there are three phases of the flow process variation degree of the two sections, namely the year 1956 to 1968, 1969 to 1986 and 1987 to 2013, and which increase by phases. The markings appear to decrease by phases and the marking in Toudaoguai section is lower than that in Shizuishan section. The key reasons of the above features are water consumption of industry and agriculture along the river and reservoir operation of Longyangxia and Liujiaxia.
