摘　　要：通过分析1987—2022年度黄河鄂尔多斯段凌情,得出2013—2022年度黄河鄂尔多斯段呈现出流凌封河日期推迟、开河日期提前、凌汛期缩短、不稳定封冻河段出现、封冻冰层变薄、槽蓄水增量减少、开河凌峰减小、凌汛灾害减少等新特点、新规律,热力、动力和河势是形成以上特点的主要影响因素。By analyzing the ice conditions in the Ordos section of the Yellow River from 1987 to 2022,it was found that from 2013 to 2022,the Ordos section of the Yellow River exhibited new characteristics and patterns such as delayed ice flow and sealing dates,advanced opening dates,shortened ice flood periods,unstable frozen river sections,thinning of frozen ice layers,reduced increase in trough water storage,decreased peak opening ice,and reduced ice flood disasters.Thermal,dynamic,and river conditions were the main influencing factors for these characteristics.
