In recent years, due to high temperature in winter in the Inner Mongolia reach of the Yellow River, the frequent occurrence of extreme temperature events, the decrease of bankfull discharge, the increase of buildings near/ cross the river, the ice prevention by reservoirs and the application of ice prevention projects, the ice regime in the Inner Mongolia reach has changed. In order to study the characteristics of the ice change in the Inner Mongolia reach, four hydrological stations of Shizuishan, Bayangol, Sanhuhekou and Toudaoguai in the Inner Mongolia reach were selected and based on the measured data of these hydrological stations, this paper studied and analyzed the characteristics and reasons of the recent ice changes. The results showed that the recent ice-run and freeze-up of the Inner Mongolia reach is postponed, the river break-up is earlier, and the river freeze-up period is shortened; the annual maximum channel storage increment is significantly increased with the maximum value occurred in recent years; the occurrence of the ice disaster is reduced. Generally, the ice prevention in the Inner Mongolia reach is still severe, and multiple measures are needed for ice prevention.
