本文在系统分析了黄河山东段各站水位—流量关系的年际、年内各时期变化规律的基础上，探讨了影响水位—流量关系的主要因素。各站年际水位—流量关系线经历了４次左移、３次右移的变化过程。年内水位—流量关系的变化因各站所处的断面位置不同而异，且逆时针绳套走向者居多。影响各站水位—流量关系变化的主要因素是断面冲淤、洪水涨落、断面形态和下游回水影响等。
Based on the systematic analysis of the relationship between the water level and the discharge at each station in the interannual and annual periods of the Yellow River, the main factors affecting the relationship between water level and discharge are discussed. Each station interannual water level - flow relationship line has gone through 4 left shift, 3 right shift process. During the year, the relationship between the water level and the flow rate varies according to the location of the sections where the stations are located, and most of the people are going counterclockwise. The main factors influencing the change of water level-flow rate at each station are cross-section scouring and silting, flood fluctuation, section morphology and the impact of downstream backwater.
