1996—1997年度黄河下游凌情主要特征表现为首封日期早；封河时气温高、流量小；封开河次数频繁，出现了历史上未出现过的4封4开现象；封冻发展期发生冰塞壅水，造成灾害；封河与开河期出现断流。在分析凌情特点的同时，分析了天气形势特点对气温、冰情变化的影响和上中游来水、水库蓄水及下游引水等因素对冰情及断流的影响。
The main characteristics of the main seasons in the lower reaches of the Yellow River during 1996-1997 were as follows: the first seal date was early; when the river was closed, the temperature was high and the flow rate was small; the frequency of sealing the river was so frequent that there were 4 open 4 phenomena that had not occurred in history; Water, resulting in disasters; closure of the river and start a stream of flow. The characteristics of the weather conditions are also analyzed. The effects of the weather conditions on the changes of air temperature and ice conditions are analyzed. The influences of upper and middle reaches water intake, reservoir water storage and downstream diversion on ice conditions and current interruption are analyzed.
