摘　　要：运用数理统计理论的相关分析方法,对黄河内蒙古段冰情时间序列自身以及对它有一定影响的水文气象序列之间的相关关系进行了分析和检验。结果表明:冰情时间序列在长期变化中都存在一定的自相关性;冰情与水文气象要素存在一定的互相关性,影响冰情的主要因素有流量、温度和风速。The paper analyzes and tests the correlation between the time series of ice regime and effected hydrometeorological series of Inner Mongolia section of the Yellow River by using the statistics mothed.The outcomes show that a) all time series of ice regime have a certain auto-relativity in a long-term variation;b) there is a certain correlation between ice regime and hydrometeorological factors,and the main factors that affect the ice regime are discharge,temperature and wind speed.
